Enter a recent race time to see your easy, marathon, threshold, interval and repetition paces.
Quick answer: Your 10K training paces depend on your current race fitness. A 45:00 10K runner (RPI 45.3) trains at 8:55/mi easy, 7:26/mi threshold, and 6:50/mi intervals. A 50:00 runner (RPI 40.0) trains at 9:50/mi easy, 8:12/mi threshold, and 7:33/mi intervals. The table below shows exact paces for common 10K times.

All paces in minutes per mile. Easy pace means "this pace or slower."
For 10K training, Threshold pace (T) is the most important session. The 10K demands sustained effort at 85–90% of VO2max for 30–60 minutes — exactly what threshold training develops. Tempo runs of 20–40 minutes at threshold pace are the backbone of 10K preparation. Interval pace develops top-end speed that makes threshold pace feel more comfortable. Easy running builds the aerobic base that supports everything else.
The most common 10K training mistake is racing every run. If your easy days feel like moderate effort, your threshold sessions cannot be properly hard — you are fatigued before you start. The second mistake is insufficient volume: most runners who race 10K well run 25–40 miles per week. You cannot out-speed a weak aerobic base at this distance.
A 45:00 10K gives an RPI of 45.3. Training paces: Easy 8:55/mi, Marathon 7:54/mi, Threshold 7:26/mi, Interval 6:50/mi, Repetition 6:26/mi. Easy running should be at 8:55 or slower — genuinely relaxed. Threshold runs at 7:26 for 20–40 minutes. Intervals at 6:50 for 800m–1200m repeats.
Once per week is standard. A typical 10K threshold session is 20–40 minutes at threshold pace (comfortably hard — you can speak in short phrases but not hold a conversation). Start with 20 minutes and build to 30–40 minutes over several weeks. Cruise intervals — 3–4 x 8 minutes with 1 minute rest — are an effective variation.
Yes — but less than for a 5K. One interval session per week (in addition to your threshold session) develops the VO2max ceiling that makes your threshold pace sustainable. Typical 10K interval sessions: 5×1000m or 4×1200m at interval pace with equal-time recovery jogs.
