Enter run and walk interval lengths plus each segment pace to estimate the repeating cycle’s average pace and speed.
The repeating-cycle average remains first. This optional planner reuses the current run/walk intervals and paces, then projects an exact target distance through full cycles plus the final partial segment, with moving finish time, added stop time, run/walk time split, and pace in both km and mile units.
Mechanical pace projection only; terrain, fatigue, transitions and conditions can change real results.
Enter one repeating run interval and walk interval plus the pace of each segment. The calculator combines the distance covered in both parts and reports the cycle-average pace and speed.
Transitions, acceleration, terrain, fatigue, and recovery effects are not included. The result is a mathematical average for the repeated interval pattern.
Use the tool first, then apply these checks to verify inputs, interpret the result, and hand it off without displacing the primary workflow.
Run pace and walk pace must use the same distance basis before they are combined. A min/km value cannot be mixed directly with min/mile, and interval lengths are time rather than distance unless stated otherwise. Confirm the pace notation and whether a value such as 6:30 means six minutes thirty seconds per kilometer.
The combined pace depends on distance covered during each time segment. Running usually covers more distance per minute than walking, so the correct cycle average comes from total cycle time divided by total cycle distance. Use the reported run and walk distances per cycle as a check on the blended result.
A projected finish time assumes the entered run and walk paces continue through the event. Acceleration, transitions, aid stations, hills, weather, fatigue, congestion, and GPS error are not captured automatically. Add known stop time separately and compare more than one pace scenario rather than treating one projection as a promise.
A race distance rarely ends exactly at a run-walk cycle boundary. A useful projection should account for complete cycles plus the final partial run or walk segment instead of rounding the number of cycles and multiplying blindly. Review total run time, total walk time, moving pace, and added stop time together when planning pacing strategy.
