Welcome to the Mac100 2025, kindly sponsored by Hawk. 

Sunday 10 August 2025 - start and finish at St Clement's Parish Hall

A fun focused cycle ride of 100km following a route which some would classify as moderate in terms of physical exertion but by all as 'outstanding' in terms of the natural beauty of the Jersey landscape through which you will ride.
We are very grateful for the tremendous support of all participants whose entry fee and any ancillary fund raising efforts will greatly benefit the wonderful work of Macmillan Cancer Support in Jersey.
You can easily set up a sponsorship page here so that your family and friends can sponsor your efforts on the Mac100.
Participants may use whatever type of bicycle they choose, including electric bikes, but excluding fixed wheel bikes, track bikes and monocycles.  The wearing of helmets will be mandatory.
There will be two refreshment stops along the route, which will be made available before the event in order that participants can make themselves familiar with the course, and signage will also be posted along the route on the day.
