Explore the pace you need to hit to reach your ultramarathon goal finish time.
Pick your distance and goal time to see the average pace you need and a full split breakdown across the day. Ultras rarely run even — aid stations, hiking the climbs, and the long slow fade all add up — so use the model as a frame and tap any split to set your own pace segment by segment.
Ease off in the second half, so your finish is a little slower than your start.

An ultramarathon is anything past the marathon — 50K, 50-mile, 100K, 100-mile, and timed events — usually on trails and measured in hours rather than minutes. Aid stations become the rhythm of the day, and hiking the climbs is part of the plan. It rewards patience, problem-solving, and a willingness to keep moving when it gets hard.
An ultramarathon is anything beyond the standard marathon — 50K, 50-mile, 100K, 100-mile, and timed events. Crossing the line is less about speed and more about not quitting.
