VDOT calculator
Estimate your fitness (VDOT) from one race result, then see equivalent times at every standard distance. Use those times to set goals on Training and Race day.
Quick guide
1. Enter a recent race distance and time. 2. Read your VDOT score and the equivalent-time table. 3. Jump to Training for workout paces or Race day for splits and fueling. Times are estimates — adjust for course, weather, and how you feel.
Choose the race you ran most recently. Accurate times from the last 1–3 months work best; tune-ups and all-out efforts are ideal.

Your VDOT score
Higher VDOT means stronger aerobic fitness. The number is not a race prediction by itself — it powers the equivalent times below and training paces elsewhere in the app.
