For this episode, I share some thoughts on the topic of "fit but unhealthy." Recently, pro triathlete Lionel Sanders shared some details about his health concerns. This came as a surprise to some as he is visually very healthy and performed at a very high level. Some have hypothesized it is due to his hyper carb fueling strategy. Others have suggested endurance training to the degree taken by professional athletes is unhealthy.

Trishul and Bob are the President and Record Keeper for the Global Organization of Multi-day Ultrarunners (GOMU). GOMU was established to supplement the existing government bodies that only recognize records of certain ultramarathon events. Both Trishul and Bob have rich histories in ultramarathon, with 100s of official events to their names. We dive into their experiences as well as the growing needs when it comes to rules and record keeping that are specific to the needs of ultrarunning. A few topics we focused on include: pacing in ultramarathon, course certification, shoe tech, and certifying record performances.

For this training recap, I unpack a four week block of training where my main focus was a continuation of speed work development with a bit more variety of inputs this time around. Hybrid workouts, fast finishes, and hills all included. I highlight the thought process behind the programming, execution, and add some tips to consider in training as I build up for a 100 mile track ultra in June!
