My Training Philosophy: Running Less, Biking More
One of the most common questions I get is about how I structure my training week, particularly how I balance running and cycling. For my Boston Marathon build, I chose to run five days per week and ride the bike two days per week. This approach stems from years of battling injuries, particularly bone stress injuries. Every time I tried running six or seven days per week—even at moderate mileage—I seemed to get hurt.
To avoid that, I started squeezing more mileage into fewer running days, reaching 75 to 85 miles per week while running just five days. On the two non-running days, I cycled for 90 minutes to two and a half hours using Zwift. Cycling allowed me to maintain a high aerobic load without the musculoskeletal strain of running. Having two full days without running each week seemed to give my body the time it needed to recover and regenerate. I felt fresher on all my runs and stayed injury-free throughout the training block, which hadn't been the case in past training cycles.
My Supplement Routine (and Philosophy)
Supplements are something I get asked about all the time, and during the Q&A, I walked through my current supplement stack. I take a fairly extensive range of supplements, but my general philosophy is simple: if you have the discretionary income and a curiosity to experiment, supplements can be worth exploring.
Each morning, I start with a whey protein shake, usually mixing 20 to 30 grams of whey protein with almond milk. I add a greens and probiotic powder, and I take L-glutamine daily, mostly for gut health and immune support. Creatine monohydrate is also a daily staple, as is an omega-3 supplement, iron (to correct low ferritin), and vitamin D3. I also occasionally use ashwagandha to support stress adaptation. Supplements aren’t magic, but they can help support an already solid foundation of training, nutrition, and sleep.
Fueling for Long Runs and Marathons: How I Changed My Approach
Fueling during training runs and races has been one of the biggest shifts in my approach over the past year. Previously, I barely fueled during runs, often going fasted. Now, for most morning runs, I eat a small snack about 30 to 45 minutes beforehand. During long runs or runs over 90 minutes, I take energy gels every 30 to 40 minutes. Science in Sport Beta Fuel gels have been my favorite because of their high carbohydrate content and easy consistency.
Proper fueling has made a noticeable difference not just in performance but also in recovery. By ending long workouts with a smaller energy deficit, my next-day performance has been consistently better.
Live Q&A Questions
Have you experienced low blood sugar or bonking during runs?
Yes, especially after I started eating before runs. I experienced mild reactive hypoglycemia about three miles into runs, which I confirmed using a continuous glucose monitor. It turned out the timing of my pre-run snack was causing a dip in blood sugar. Adjusting the timing—either eating earlier (45–60 minutes before) or just minutes before starting—helped eliminate the issue.
What’s your advice for returning to running after an injury?
I recommend the walk-run method, regardless of experience level. Coming back slowly with a run-walk protocol reduces injury risk and helps you rebuild fitness without overwhelming your musculoskeletal system. Even elite runners use this strategy when returning from time off.
Does cycling help build your aerobic base for running?
Absolutely. Cycling has been a key part of maintaining and building my aerobic fitness while sparing my body from the pounding of running. Two days of cycling per week allowed me to maintain a high training load without increasing injury risk during my Boston build.
What are your thoughts on nitrate supplements like beetroot juice?
Nitrate supplements have strong evidence for enhancing performance, especially in clinical or less-trained populations. For highly trained athletes, the benefits are likely smaller but still potentially meaningful. They are safe and can also support cardiovascular health, so if you're curious, they are worth trying.
What’s your approach to warming up before races and workouts?
I’m a big believer in long, extensive warmups—typically 4–6 miles of easy running with some race-pace surges. You want to feel warm and ready when the race starts, not spend the first few miles getting into rhythm. A proper warmup can make a big difference in early race pacing and overall performance.
Do you lift after long runs or interval workouts?
Yes, but strategically. I usually lift after my Sunday long runs because it’s easier to stack hard efforts on the same day and allow easier recovery days afterward. I do my best to get into the gym immediately after the run while I’m still warm, even though it's not always easy.
What do you think about concerns over eating high amounts of carbs during marathons?
I think it's mostly fear-mongering. Race-day fueling is not the same as everyday eating. Consuming 80 grams of carbohydrates per hour during a marathon is performance-enhancing and supports recovery. There’s no strong evidence that race-day carb intake leads to metabolic disease when your daily nutrition is solid.
How does race-day nutrition affect your recovery afterward?
Proper fueling during the race has a huge impact on how you feel in the days afterward. After Boston, although I still had muscle soreness, my recovery was far smoother compared to previous marathons. I believe fueling adequately during the race played a major role in that.
If I’m a slower marathoner (around four hours), should I train differently than you?
Not drastically. You don’t need to run more hours per week, but your long runs should probably be longer in duration compared to mine. I would recommend aiming for three to three and a half hour long runs, even if your weekly mileage stays relatively modest.
What’s your approach to returning to training after illness?
Slow and steady. I focus first on building back volume at low intensity and delay introducing intensity until I feel fully recovered. Low-intensity walking, biking, or easy running can be good first steps before resuming hard efforts.
Is cycling useful even if your running mileage isn’t maxed out yet?
Definitely. Cycling can be a supplement to running even if you’re not at your maximum running volume. It’s an excellent tool to add more aerobic training stress without the same injury risks as running.
How does L-glutamine help with gut health?
L-glutamine may help support the gut lining and reduce gastrointestinal permeability, especially important during periods of heavy training or exercising in the heat. I’ve added it recently to help support digestion during intense marathon training blocks.
Final Thoughts
This Q&A was a blast. I’m so grateful for everyone who tuned in, asked thoughtful questions, and stayed engaged throughout the session. Going forward, I’m considering doing more Q&A sessions, maybe focused more narrowly on specific topics like fueling strategies, supplements, or injury prevention.
If you have any feedback or ideas for future Q&As, I’d love to hear them. Thanks again for being part of this awesome community. I'll see you next time—whether it’s here, on X, or maybe even in real life!
