With Pæthos in the shop for a tune, this seems like a good time for a post-op update.

On March 7, I had a metal mesh plug implanted in my heart in order to close a hole between my two atria: a possible cause for my past and potential future strokes. It’s been seven weeks since the operation, so let’s review how my return to fitness has gone… And, of course, the prognosis going forward.

So grand... and living!

So grand... and living!

Phase One of my recovery consisted of 10 days completely off the bike. I had incisions into both of my femoral arteries that needed to fully heal before I could do anything as strenuous as walking, climbing stairs, or having a bowel movement, never mind cycling! I had tenderness and a sizable hematoma in my groin, and heart palpitations that mostly dissipated over time. After a few days I started doing short walks around the neighborhood, working up from 1,500 meters to 3 kilometers, but my athletic Fitness (aka CTL, or Chronic Training Load) dropped from a pre-op 56.6 down to 44.6.

During Phase Two, I got back on the indoor bike trainer. The only constraint my cardiologist had given me was to keep my heart rate below 110 BPM, which was the perfect level for me to keep up with one of Zwift’s “robo pace partners” at 1.5 W/kg: a mild but not sedate pace. I Zwifted for 13 of the next 16 days, steadily increasing duration from 15 minutes to 30, 45, 60, and eventually 90 minutes at a time. Being back on the bike felt great, but I wasn’t riding hard enough or long enough to keep my Fitness from continuing to fall to a low of 33.4. The tenderness ended and my hematoma started to fade, but I still had a few palpitations from time to time.

On April 1, 25 days after my surgery, my cardiologist gave me the green light to gradually resume all normal activities, doing whatever felt right for my body. And just in time, because Austin has been having truly glorious spring weather.

That was my signal to begin eagerly-awaited Phase Three: my return to outdoor riding, while gradually increasing both duration and intensity.

Distance and duration came easily. I started with a couple 90-minute rides, and over two weeks moved up to 2-hour 50 kilometer rides, then 3½-hour 80 kms. So long as I stayed below 90% effort, I could ride all day.

Intensity came more slowly. Between my own innate caution and continuing cardiac palpitations, I wasn’t very eager to push my maximum heart rate. So I avoided hills for a couple weeks before gradually testing myself on those inclines, where I reached ≈150 BPM.

Since I got back on the bike, I’ve ridden 29 of the past 39 days, totaling 770 kilometers, or an average of about 20 km per day. To my delight, my partner has already commented on the return of my “distinctive markings”: her terminology for my stark cyclist’s tan lines.

Aside from the joy of being back outdoors on the bike, seeing my Fitness numbers making upward progress has been really encouraging. Long outdoor rides have been vastly more effective than Zwifting in raising my CTL, which has climbed to a recent (but still tepid) 40.6.

But I’m still a ways from where I need to be for major events or even spirited group rides. And I’ll lose a little Fitness this week, while the bike’s in the shop.

However, all that riding has helped me begin to get clarity about what this summer’s riding might look like. My hope all along was that I could do my third 100 KM Fire Ant Tour in mid-June, and that I’d be able to do a creditable (if shortened) ride for my remote Pan-Mass Challenge in August. At this point, those look reasonably likely.

But if I continue to do well, there’s a chance I might be ready earlier, and could ride the Stampede on the Chisholm Trail, another metric century that takes place in two weeks, or two months post-surgery. That would be extra cool because it’s another local event that I’ve never done before.

It’s delightful being back out on the open road again, and looking forward in anticipation of upcoming rides!

For reasons I’ll explain in a second, improving my diet became a critical consideration following my stroke. But I had lots of questions about the areas where healthy eating directly conflicts with sports nutrition’s best practices for endurance athletes. I decided to get answers from a professional, and this blogpost summarizes what I got out of consulting a nutritionist for the first time in my life.

This is one of those posts where it’s not clear whether it belongs on my general blog or here on my cycling-specific blog. Since I came at this from a cyclist’s perspective, I decided to post it to the latter, so that other cyclists would more readily find it. But most of this is equally relevant to my non-cycling readers.

Where I Started

The statistics say that 25 percent of stroke survivors will have a second stroke. And, according to the hospitalist who was in charge of me during my hospitalization, the greatest determinant of whether you have another stroke is diet. Survivors who didn’t change to a heart-healthy diet had the most readmissions, in contrast to those who took dietary advice to heart.

What did she specifically advocate? This:

  • Reduce inflammation and chances of developing diabetes by cutting intake of simple sugars
  • Reduce cardiac risks by limiting dietary fat intake, especially saturated and trans fats
  • Avoid hypertension by reducing intake of table salt and highly processed foods
  • Maintain healthy blood volume by staying fully hydrated
Sports Nutrition for Endurance Athletes

That was the first advice I got following my stroke, and – as a Type A personality and someone with an intense fear of stroke – I took her opinions extremely seriously. Even though I’m significantly younger, healthier, and more active than most stroke survivors, improving my diet seemed, at that time, to be a matter of life and death.

However, as an endurance cyclist, two of those strictures are problematic for me. Simple carbs are the preferred and primary fuel for athletes; would I be risking my health by continuing to emphasize them in my diet? And it’s pretty hard to avoid chronic dehydration if you’re riding hard in the Texas sun for a multiple hours every day.

Although I’ve stayed on top of changing dietary recommendations for decades, these contradictory needs convinced me that it would make sense to consult a nutritionist for the first time in my life.

Another factor is that I was very concerned about weight loss. From 2011 through 2022, my body weight stayed in a narrow range, mostly between 76 and 79 kg, averaging out at 77.3. But in the last five months of 2022 I suddenly and inexplicably dropped 6½ kilos (15 lbs). I gained about half of that back, but then lost another 3½ kg in the weeks following my stroke, bringing me down to an adult-era low weight of 71.2 kg (157 lbs). A nutritionist could help me figure out how to stem my ongoing weight loss while simultaneously cutting both carbohydrates and fat out of my diet.

More Medical Advice I Got

I’ve already outlined the alarmist attitude that my hospitalist instilled in me right after my stroke, and where that advice led me.

But I immediately started getting contradictory advice from every other healthcare provider I talked to.

A week after my stroke, I had a followup with my family physician, who told me that nutrition was a long-term concern and not to overdo any drastic changes to my diet. But as a PCP he’s a generalist, so I remained skeptical, while making sure I got a referral to a nutritionist out of him.

A week after that, I had a followup with my neurologist, whose attitude was that nutrition is just about general health and preventing blood clots, which is more of a cardiologist’s domain.

It took another month before a long-awaited meeting with my cardiologist. His attitude was another surprising counterpoint to the hospitalist. He also claimed that diet is purely a long-term concern, saying both “Go eat a pizza if you want,” and “Eating heart-healthy is not the most pleasant thing.”

After all that, I really didn’t know what to think. The obvious consensus was that diet wasn’t the smoking gun that the hospitalist had portrayed. But it was still hard for me to cast aside her staunchly-held opinion, since it was the only obvious thing that I could control.

But maybe my nutritionist would provide a decisive opinion…

My Nutritionist Experience

I’ve never really thought of nutritionists as a highly skilled profession. As I see it, there are two main aspects to the job.

One part is staying up-to-date on the ever-changing “science” – separating genuine dietary knowledge from the deluge of biased pseudo-science – and distilling that down into a form that’s digestible for their uninformed clients.

This would be of some benefit to me. Having paid attention to sports nutrition for 25 years, I’m pretty well-informed. But I’m less up-to-date on heart- and health-related topics, and never had to deal with problematic weight loss. And it’d be nice to get the current scoop on perpetual debates like “Are eggs good or bad?” and “Which is healthier: butter or margarine?”

The other – and possibly larger – aspect to the job is similar to that of a therapist: talking with clients and trying to manage them into growing the self-discipline required to make lasting dietary changes.

As I mentioned above, I’m a Type A; I don’t need external support once I’ve decided to change my behavior. So the coaching aspect of the nutritionist’s job is really of no value to me.

The most valuable and immediate advice she game me was when she confirmed what my other healthcare providers had said: that I didn’t need to approach dietary changes with a crisis response and rigidity, and that no one individual choice is gonna kill you. I didn’t need to eliminate all fats and simple carbs from my diet, after all. I was already living a pretty healthy lifestyle, and the emphasis should be on fitting increasingly beneficial habits into a healthy diet whose results compound over time.

But beyond that high-level advice, after four meetings in five months, I’m still not convinced that a nutritionist brings a ton of expertise and value to the table. My nutritionist mostly just repeated standard advice that variety is most important and that even “bad” foods are okay when taken in moderation.

At the same time, I don’t want to sell her short. I did get some novel, useful information from her that manifested in some dietary changes I wouldn’t have considered otherwise. So let’s take a look at those…

Specific Dietary Recommendations

It’s pointless talking about the changes I’ve made without first reviewing my diet prior to my stroke. After all, I made a number of significant improvements over the years, and those remain a noteworthy part of the overall equation. Here are some positive features of my baseline diet that I’ve observed for some time:

  • Daily multivitamin and psyllium husk fiber supplements
  • Replace full- and low-fat milk with fat-free/skim
  • Virtually eliminate beef intake
  • Never, ever add salt to anything (except corn on the cob)
  • Cook at home; eating out is a rarity
  • Emphasize broccoli as my primary leafy vegetable
  • Replace ice cream with sorbet/sherbet or fruit pops
  • Replace high-fat sauces like alfredo with low-fat tomato sauces like marinara
  • Keep an eye on the ever-changing recommendations regarding eggs, butter vs. oil-based spreads, etc.
  • Reduce or eliminate soft drink intake, replace with fruit juices like OJ, apple cider, lime- and lemonade, and fruit punch
  • No significant intake of caffeine outside of major events and medicinally
  • No alcohol in any form, ever, period

Even after accepting that the hospitalist’s alarmist warning was misguided, I still wanted to make incremental improvements to my diet. Specifically, I wanted to reduce fats, sodium, and simple carbs (beyond my athletic needs). Between my own research and input from my nutritionist and cardiologist, I’ve landed on the following new guidelines:

  • Daily statin prescription to keep cholesterol down, even tho my numbers were never high
  • Daily Omega-3 fatty acid supplements (algae-based rather than fish oil)
  • Whey protein isolate powder supplement
  • Eliminate or curtail high-fat foods, particularly commercially-prepared baked goods, cocoa, frozen pizza, etc.
  • Read labels to select lower-fat chocolate candies, and healthier salty snacks that are baked or use healthier oils like avocado
  • Reduce overall cheese intake, and use 2% milkfat cheese over full-fat
  • Sauté and stir-fry in avocado oil rather than corn or peanut oils (it has a higher smoke point than olive oil)
  • Substitute ground turkey and pork for ground beef
  • Supplement wheat-based pastas with lentil-based
  • Favor lower-sodium soups like corn chowder; at some point start making my own soups
  • Expand meal repertoire by reintroducing or increasing things like:
    • Boiled chicken
    • Oatmeal (with raisins, sunflower seeds, and dried fruits)
    • Baked beans
    • Mashed potato
    • Sweet potato
    • Nuts, especially hazelnuts
    • Apples

Conclusion

Despite having a longstanding interest in sports nutrition, I never bothered consulting a nutritionist until now. I always doubted whether a nutritionist could add any useful information beyond what any self-educated layman could glean from readily-available public sources.

After a 5-month engagement, I mostly stand by that opinion, although it does need to be refined. My nutritionist helped refute the bad advice I got, and provided some suggestions that were truly useful. But those were largely tactical adjustments, rather than significant course changes. So she definitely did add value… just perhaps not as much as I had hoped for from a licensed medical professional.

I’d be temped to conclude that it wasn’t worth the money, but my health insurance covered the entire tab! All it cost me was time, so in that respect I got way more valuable insights than I paid for.

But I’m still skeptical about whether consulting a nutritionist is worth it for most cyclists or your average non-cyclist. If you have a very particular situation, like I did, then perhaps it would be. But if you’re interested enough to have questions about nutrition, you’re probably also motivated enough to find the answers for yourself, rather than pay someone else to do it for you. A nutritionist really isn’t privy to any information that can’t be found elsewhere.

It absolutely does make all kinds of sense for a cyclist to learn the basics of sports nutrition, and there’s no shortage of available material. For myself, my bookshelf includes the fairly lightweight “Bicycling Magazine’s Nutrition for Peak Performance” by Ed Pavelka, and the more comprehensive “Sports Nutrition for Endurance Athletes” by Monique Ryan. But these days there’s ample other sources, too.

That’s it! Now let’s go eat to ride, and ride to eat!

Friday I had heart surgery. Even though it was via intravenous catheters and I should fully recover, the recuperation period is still gonna blow a hole in my training and fitness. So this is a good time to get you caught up on what I’ve been up for the past two months, and where things go from here.

So far, 2025 has been a little bit of up-and-down, and a little bit of in-and-out. I took a bit of a break when the calendar flipped, and then it was an odd mix of indoor and outdoor riding, mostly dictated by Austin’s variable winter temps.

On the indoor side, I’ve logged about 1,000 km on Zwift, focusing primarily on riding a dozen+ new routes, advancing another four XP levels, and participating in eight delightful PMC group rides, which have just finished up for the season.

But knowing that a surgically-induced enforced break was coming, I did my best to ride outdoors as much as the weather would allow. February in Austin began and ended delightfully, allowing me to rack up over 500 real-world kilometers on a dozen rides, including my first two Friday Truancy group rides since my stroke at the start of October.

My final ride before the operation was last Wednesday’s 80 km trip out the Southern Walnut Creek path to Manor, which was my longest ride – indoor or out – since my stroke. It also marked my max Fitness level for the year (a pretty moderate 56 CTL), having finally recovered all the Fitness I’d lost by resting at the start of January.

So that brings us to the beginning of March, and Friday’s heart surgery. If you want all the details, you can read the accompanying post in my general blog, but here I’ll limit myself to the short- and long-term impacts to my riding.

In the short-term, the surgery is going to require some recuperation time, which means time off the bike. It’s really important that the two incisions into major veins in the hips are allowed to close up and fully heal before attempting any kind of exercise. If things go well, this week I’ll start doing some short walks. A week after that I might introduce some low-intensity work on my partner’s elliptical trainer. Then some easy rides on my indoor trainer. But for the next month I have to always keep my heart rate below an extremely mild 100-110 bpm.

I’ll have some post-op testing and a followup with my cardiologist in about three weeks, at which point I hope to get the green light for a gradual return to actual training. Over the next several weeks of minimal exercise, my Fitness is going to plummet, and April and May will be spent trying to get back to last week’s Fitness level.

And what will the rest of the year look like? It’s hard to say until after that followup appointment. I think I can expect a full return to endurance riding, but when and how long that’ll take is unknown. I’m almost certainly not doing the events I’d hoped to do in April: the American Stroke Association’s CycleNation charity spin-bike ride; and the Red Poppy Ride century. But I might be ready for June’s 100k Fire Ant Tour. We’ll see how it goes.

And what about riding remotely for August’s Pan-Mass Challenge? As I said in December’s annual summary post, that’ll remain a complete unknown until May, so I’ll defer my registration until I have more clarity. Hopefully I’ll be in shape to make it a good couple days of riding, to “properly earn” my sponsors’ donations to DFCI, even if perhaps it might fall short of the traditional 300 kilometers.

But I do expect I’ll be able to return to the endurance riding that I love. It’s just a question of when, and how long it’ll take to train back up to the fitness I need to complete such rides.

But until then I guess I’ll take a few weeks of enforced relaxation!
