Cycle 57 miles around Arran followed by climbing Goatfell, the island's highest peak at 2,866 feet all in a bid to tackle poverty and fight disadvantage in Glasgow.
If the idea sounds appealing but your stamina is not, we've got cycle-only and climb-only options too.
The action takes place on Saturday 7 June 2014.
Minimum sponsorship for the Duathlon is £100, or £75 for the cycle-only or climb-only events.
Glasgow City Mission will provide:
- Return foot-passenger ferry ticket from Ardrossan to Arran
- Food and showers at our Challenge Base – the Ormidale Sports Centre, Brodick
- Support vehicle for cyclists
- Fundraising toolkit incl sponsor forms, T shirt and top tips to engage your friends & family
