How to use the result
Pace is a budget, not a promise.
Start with an achievable finish time. Use the per-mile or per-kilometer target for steady sections, then compare actual checkpoints rather than reacting to one fast opening split.
For common targets without entering a time, open the running pace chart. For hybrid events, keep work stations and transitions separate from running time.
