Run Split Planner

Generate a per-km or per-mile split plan from a target finish time. Choose between even pace, negative splits (start slower, finish faster), or positive splits (start faster).

  • Even splits – same pace for every km
  • Negative split – start 3% slower than average, finish 3% faster
  • Positive split – start 3% faster, finish 3% slower
  • Custom race distances are supported in km or miles
