Marathon Race Pace Calculator

The marathon is the ultimate running challenge. At this distance, pacing is everything — a 10-second-per-kilometre error early on can cost minutes late in the race. Know your target splits before race day.

Enter either your goal finish time or your goal pace per kilometre — the calculator works both ways, giving you your projected finish time, km/h speed and even splits throughout the race.
