What did your training look like for these races?I have run and paced at both Run Rabbit Run in Steamboat and Bighorn in Wyoming. Both are well run races and have a great post race celebrations. Bighorn is known for mud, which I experienced pacing a friend. I ran the race this past June and it was hot and dry. I thought we maybe caught a break this year, but it was still difficult. Run Rabbit is also a challenging course, with some sections around 10k feet. It typically gets cold over night there. Of course Run Rabbit is in September so could interfere with archery elk season. Happy to share more if you are interested in either of those races.
For perspective, I'm a mid to back of the pack runner and went over 33 hours for both of these races. I followed a 26 week plan with mini cycles of 3 weeks building and one "recovery" week. In the meat of the 26 week schedule, I averaged low to mid 60 mile weeks, with a few peak weeks hitting 70 miles. Both cycles included a 50k race and 50 mile run. For Run Rabbit, I ran 50 miles in an overnight race (partly to get used to running in the dark). For Bighorn, I ran Rim-to-Rim-to-Rim in the Grand Canyon (48 miles and about 12k feet of vert). Both cycles also included few weekends with back to back 20+ mile runs.
