Ultramarathons in September
Cool mornings, golden aspens, and a whole summer of training behind you.
September may be the runner's month. Wasatch and The Bear in Utah run through the aspen turn, and fall 50Ks get cool starts and warm middles. The heat has broken; your fitness hasn't.

- Late May: start the 16-week 50K plan
- Late August: peak week
- Mid-September: race day
Your training season. All summer, all build. Long days make long runs easy to fit, but heat makes them harder. Run early, treat the late-August peak with respect, and arrive at September fresh.
Masters Athlete Insights
