Run Training Paces Examples
Establishing the right training paces is important for effective and injury-free running. If you are aiming for a personal best, building endurance, or simply enjoying the sport, varying your intensity across easy runs, tempo efforts, and intervals is key. How to calculate these vital paces across diverse scenarios.

25-minute 5K
A runner enters a recent 5K time of 25:00 to derive Daniels training paces.
A 25-minute 5K is a 300 second per km race pace and gives a VDOT of 38.3, with easy runs at 6:33 per km, threshold at 5:16, and intervals at 4:45.

The gap between easy and interval pace is the whole point. Most runners train their easy days too hard, so anchoring the easy pace near 6:33 here is what leaves room to hit the quality sessions.

Faster 5K
The same 5K distance, but a quicker 22:00 finish.
VDOT rises to 44.5, shifting easy runs to 5:49 per km, threshold to 4:40, and intervals to 4:13.

Three minutes faster over 5K lifts every training pace by roughly 30 to 45 seconds per km. As fitness climbs the whole ladder shifts, so retest every few weeks rather than clinging to old paces.

10K input
A runner instead enters a 50:00 10K time.
VDOT lands at 40, with easy runs at 6:20 per km, threshold at 5:05, and intervals at 4:36.

A longer race input often gives a more honest fitness picture than a short one, since it captures endurance too. Use your most recent hard race regardless of distance, as the model equates them through VDOT.
- 4
Half-marathon input
A runner enters a 1:45:00 half marathon.
VDOT is 42.6, with easy runs at 6:01 per km, marathon pace at 5:10, and threshold at 4:50.

For marathon training the half-marathon input is ideal, since it gives a marathon-pace estimate grounded in real endurance. Keep threshold work capped near 20 minutes continuous, as the tool's description notes.
