Guy Martin is currently cycling around the coast of the UK, trying to beat the current Guinness World Record of 22 days of riding the 4,800 mile route around the UK coast line, set in 1984 by Nick Sanders.

This is Guy’s last challenge of the year, where the aim is to complete the distance by Christmas Day, averaging 250 miles a day and we hope in 'kind weather'.

Guy says “It’s further than you think” - "It's not the best time of year to be doing it" and proudley shows off his 2017 Calendar, before he head off to the pub for a 'quick pint' before bedtime for an early start on Wednesday 7th December. 

The programme will be aired on Channel 4 on Thursday 29th December, 9pm.
