    Erg Split Calculator

    Put in a split, watts, calories or speed and you get all the others straight away, using the same formulas as the Concept2 monitor. It also works out the split you need for a target time, a whole piece, and what one second on your split is actually worth.

    How it works

    1. 1Pick what you know: a split, watts, calories an hour, speed, or a target time for a distance.
    2. 2Type it in and the rest fills in, including a calorie figure for your own body weight rather than the monitor’s.
    3. 3Check the table of nearby splits to see what a second quicker or slower does to your watts and your 2k.

    Example

    A 2:00/500m split

    • About 203 watts
    • About 997 calories an hour on the monitor
    • An 8:00 2k
    • One second quicker (1:59) is about 5 more watts and a 7:56 2k
