Marathon prediction 4:21:27 hh:mm:ss (56 day Tanda equation, in 7 days time).
227 km in 26 hours 52 minutes (averaging 4.1 km at 07:05 mm:ss per km taking 28:47 per day).
You ran on 17 of the last 56 days (30%), an average of 13.4 km taking 1:34:51.
On those days, this was the equivalent effort that a 3:56:43 hh:mm:ss marathon runner might do every day.
Your daily average (circles, lighter red for the older ones), the Tanda lines for marathon runners of different speeds (thin lines) and your progression over the last 56 days ending with a blue circle showing your current 56 day average.
Pushing the blue circle to the right (doing more distance) and upwards (faster) will make you fitter.
