5K
Your 5K plan shouldn't be 'just run 3 times a week'
The coach that runs with you
A fast 5K is built with precise intervals, easy runs that allow recovery, and a taper that leaves you fresh. All calculated from your real VDOT.

You run 3, 4, 5 times a week. Always at the same pace. And your time doesn't improve.
The problem isn't that you don't train enough. It's that you train without structure. Without pace zones, without calibrated intervals, without easy days that let your body absorb the load. Your body needs different stimuli to improve — not more kilometers at the same pace.
Your plan inside
This is a 5K plan with PRB
Speed with purpose
It's not 'run faster'. It's intervals at your exact Interval pace — your VDOT determines that pace. 5-8×1000m or 8-12×400m with calibrated recovery.
2 quality sessions per week.
5 zones, each with a purpose
In a 5K, the Interval and Rep zones are the ones that move the needle. PRB calculates them to the second with your VDOT. A 5-second difference per km in intervals completely changes the stimulus.
VDOT + 5 active zones.
VDOT + 5 active zones.
Real recovery
Easy days are as important as quality days. If you run hard every day, you don't absorb the load. Your plan alternates intensities with logic.
3-5 sessions/week balancing quality and volume.
Weekly adaptation
If you can't complete intervals one week, the plan reorganizes the next. It doesn't repeat what was missed — it adjusts what's coming.
Weekly recalibration.

Frequently asked questions about your 5K plan
8-12 weeks is typical. It depends on your current level and history.
Yes. A 5K is run near VO2max. Without specific intervals at that zone, you're not training what you need for race day.
Yes. 3 well-structured sessions are enough for most runners. What matters is quality, not quantity.
It depends on your current VDOT. PRB calculates a prediction based on your real data, not generic averages.
