Ultra Running Pace Calculator
Plan your next race from 5K to 200 miles. Calculate your running pace, estimate finish times, and build a more realistic ultra race plan.
1. Your running pace
Enter your average pace to estimate your race finish time.
Your estimated finish
A planning estimate based on your pace and selected adjustments.
Including terrain and planned stops.
For ultras, plan around terrain, fueling, fatigue, and aid-station time — not pace alone.
Finish-time chart: 5K to 200 miles
Compare estimated moving times and finish times including your planned stops.

These estimates assume a constant average pace with a simple terrain allowance. They do not predict elevation effects, fatigue, weather, or technical trail conditions. Real race times can vary significantly.

Ultra running pace calculator FAQs
How do I calculate my ultra finish time?
Multiply your average pace by the distance to estimate moving time, then add planned aid-station stops and breaks. For trail races, consider elevation, technical terrain, weather, and fatigue.
What is a good pace for a 100-mile race?
There is no single ideal pace. It depends on the course, elevation gain, cut-offs, conditions, experience, and goals. Plan from a realistic finish time and allow for stops and unexpected delays.
How do I account for aid stations?
Enter your expected total stopped time, including aid stations, drop bags, clothing changes, and breaks. Detailed race plans can estimate each stop separately.
Can I calculate a 200-mile race?
Yes. This calculator includes 200 miles, approximately 321.9 kilometres. Treat the result as a rough estimate and create a separate fueling, sleep, crew, and contingency plan.
Is the terrain adjustment accurate?
It is a simple percentage adjustment, not a validated elevation model. For a better estimate, use course-specific data, elevation profiles, race cut-offs, and your results on similar terrain.
