Thanks! That's a good time for a 50k! This same YouTuber (Nate) just did the Leadville, CO 100 ultra marathon. I think he finished in just under 13 hours. I think success will definitely boil down to proper training. It's a pretty big commitment, as you well know, but I can't imagine life without some of these kinds of challenges from time to time. Are you back to 100% injury-wise now?
