Around 1,300 people taking part
For the 1,300 or so people taking part in the Manx Telecom Parish Walk, today is the big day.
The event sees people tackle all or part of an 85-mile route, which visits each of the Isle of Man's parishes along the way and has a 24-hour time limit.
Some are aiming to win, others to go the full distance, make it to Peel or some other personal target.
Many are also raising money for charitable causes by taking part.
Former, multiple winner Jock Waddington told Manx Radio who he thought would win the men's and women's races:
Voters go to the polls for Manx General Election
Upgraded CCTV for Ramsey to be funded by criminal cash
Public counters closed due to staff shortages
Church service wants people to think more about impact of disabilities
