the next one.
RunFolio keeps the races you have already finished. These are for the one you are training for. Free, no account needed, and every result has a link you can send to whoever coaches you.
Training plan generator
Turn a 5K or 10K time trial into target paces, predicted finish times and a week-by-week plan for a half or full marathon.
OpenPace calculator
A distance and a time give the pace you ran, per kilometre and per mile. A distance and a pace give the finish time, with the splits to hit on the way.
OpenRace time predictor
One result you have already run, turned into what it is worth at 5K, 10K, the half and the marathon.
OpenSplit planner
A goal time as the number you need to see at each marker — even, a negative split, or the fade you would rather plan than discover.
OpenKhadakwasla Ultra training plan
The full ten-week block for the 25K, 35K and 55K at Khadakwasla on 22 November 2026 — every session, the pace zones, the fuelling, and what to do on race morning.
OpenThese tools give general guidance built from published running performance tables. They are not coaching, and they know nothing about your injury history — talk to a professional before starting a new training block.
