Temperatures will rise to 22 degrees Celcius
'Warmer weather means there won't be any Parish Walk records broken today' - that from current record holder, Richard Gerrard at the start line this morning.
He holds the overall record for completing the course in 14 hours, 40 minutes and eight seconds, and has won the last three race events.
Ronaldsway Met Office is forecasting temperatures up to 22 degrees Celsius today.
He says how he plans to power through regardless:
