Ultra Marathon (50-100mi)
What it takes
The 50-mile to 100-mile ultra marathon demands months of structured training and teaches you to manage nutrition, sleep deprivation, and mental fatigue across 12-30+ hours of effort. Comrades (90K), Leadville 100, Western States 100, and Grand Canyon R2R are iconic events. Ultra runners over 50 make up nearly half of most fields — endurance and experience count more than speed.
