Set finish time, pace, speed, or any 200m split; the rest stay even.

An 800 in 2:30 is 3:07/km and 75 seconds per 200 m even. Change finish time, pace, speed, or any 200 m clock; the rest stay even. Two laps of 400 m. Yasso 800s are a different question — they map a marathon clock onto 800s as a heuristic.

What this result means

The 800 sits between sprint and endurance. This page converts a two-lap goal into pace, speed, and 200 m checkpoints. Edit any of those numbers — the rest stay even. It does not model a 400-plus-kick; even splits are the table.

800m repeats add rest. Yasso 800s ignore your 800 PB and use marathon hours and minutes as 800 seconds — a named workout, not this identity.

2:30 is 3:07/km. 2:00 is 2:30/km. 3:00 is 3:45/km. Even 200s at 2:30 are 37.5 seconds, shown to the nearest second.

A 2:10 800 is 65-second laps. Type 2:10 (2 minutes 10 seconds).

A 2:00 800 is 2:30/km and 30-second 200s even. Those are goal 800 times, not Yasso mappings and not a repeat session with rest.

Calculation method

Pace = time ÷ 0.8 km. Splits every 200 m. Change any one of those numbers and the others rescale to the same even pace. Displayed times round to the nearest second.

Exact arithmetic on 800.00 m.

Championship 800s are rarely even. The table is still the average you must run.

Frequently asked questions

What pace is a 2:30 800?

About 3:07 per kilometre. Type 2:30, 3:07/km, or 38 seconds at 200 m — the table stays even.

Is this Yasso 800s?

No. Yasso maps a marathon goal onto 800 times. This page is an 800 goal time.

How many laps is 800m?

Two laps of 400 m.

Should I use Yasso 800s or 800m repeats instead?

Use this page for one 800 m goal time and even 200 m splits. Use Yasso 800s to map a marathon H:MM onto 800 times. Use 800m repeats for pace, rep count, and rest as a session clock.
