The recent heatwave accompanied by relatively high humidity has made for difficult running conditions and many people struggled with races over the weekend.
Use the spreadsheet calculator below to take the guess work out of how to alter your runs to accommodate the heat. You can work out your ideal pace for any given temperature and humidity so you can train safely in the heat (should we have anymore hot weather!).
I have adapted this calculator by including a calculation that uses both the actual temperature and the humidity (if known) to create what is known in Canada as the Humidex Index or a ‘feels like’ temperature. You’ll see that for example on Tuesday of this week when it was over 30c and the relative humidity was 78% the Index was much higher than the basal temperature. In lower temperatures the humidity doesn’t have quite the same effect.
Anyway enjoy using it – any questions please contact me.
