five mile pace and finish time calculator

The five mile is 8046.72 metres — 8.047 km, or 5.000 miles. Enter a pace and this gives the finish time, or work backwards from a target.

Pace, minutes per km = 5.3
Plus seconds = 0
Or a target time, hours = 0
Target minutes = 0
distance_m = 8046.72 = 8046.72
distance_km = 8046.72 / 1000 = 8.046 72
Pace per kilometre = 5.3 * 60 + 0 = 318
Finish time = 318 * 8.046 72 = 2558.86
Speed = 318 > 0 ? 3600 / 318 : 0 = 11.3208
Speed in metres per second = 11.3208 / 3.6 = 3.144 65
Pace per mile = 318 * 1.609344 = 511.771
target_seconds = 0 * 3600 + 0 * 60 = 0
Pace needed for the target time = 8.046 72 > 0 && 0 > 0 ? 0 / 8.046 72 : 0 = 0
Halfway split = 2558.86 / 2 = 1279.43
Quarter split = 2558.86 / 4 = 639.714
Pace per 400 m lap = 318 * 0.4 = 127.2
Track laps = 8046.72 / 400 = 20.1168

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

Scenarios & local history

The formula

Splits assume an even pace. Most runners are better served by starting slightly slower than target and finishing faster.

The mile is exactly 1609.344 m, so the pace conversion here is exact rather than rounded.

8046.72 metres, which is 8.047 km or 5.000 miles.

Divide the target time by the distance in kilometres. The calculator does it in the "pace needed" row.
