do need a mara time for it, though... i still don't have a standalone time for 26.2 (my one and only time is from IM!)
does it only work for the IM Switzerland course? I can imagine the times could be different for Wales, for example...
Hi Andrew, all times needed are in mins – it does say that just above the equation but is easy to miss, so I've made it bold it stand out more.
Let us know if it works for you!
