AM - Day off from running. I got on the treadmill for about 30 seconds and could feel some weird soreness in my groin, so I decided today would be a good day for recovery. It's been 10 days since I took a day off and the most active weekend I've had post-injury. I did 20 minutes worth of elliptical and walking backwards. Really good points made by Running Writings in the post 52 Lessons Learned from a year of weekly writing. So many good ones but here are a few of my favs - 3. When it comes to "core strength" for runners, strength in the hips and glutes is most important for preventing injury 25. A headwind can stifle your running pace by a significant degree, and a tailwind only aids you about half as much as a headwind slows you down. But on the bright side, you can cut 80% of the air resistance by drafting behind another runner! 26. Marathoners should try to do some longer runs right away in the morning in order to improve their body's fat-burning capabilities. "Fasted workouts" will be slower and more difficult, but they can stave off hitting the wall in a marathon by shifting the energy substrates you rely on while running. 30. Ice baths can help reduce muscle soreness and maybe even avoid a drop in performance the day after a hard effort. A large part of the benefits appear to come from the water pressure, not the temperature, so standing in a swimming pool might be nearly as good as sitting in an ice bath. If you do want cold temperatures, don't go below 50° F. 39. Missing a few hours of sleep on a single night is unlikely to impact your performance significantly, though it can increase your perceived exertion level. However, chronic sleep deprivation leads to undesirable changes in hormone levels.
