Found this in the volunteer section.
'For a reduced entry fee of £25 riders can act as Tail End Charlies. Each pair will be allocated a 20-30 mile section of course which you will be required to ride with a two-way radio, staying behind the last rider making sure the course is clear. At the end of your section you will hand over to the next pair - you can then either continue on the route and finish the course, or return to race HQ.
All Tail End Charlie riders have the option of completing the entire course, as long as you ride your allocated section behind the last rider. You'll also get all the same goodies as full priced entries and be eligible for spot prizes.
For more details about the Tail End Charlie role please email more@kielder100.co.uk'
I rode at the 'Brighton Big Dog' last weekend and am really keen to do a bit more off-road stuff, can't make this date, but if they run it next year I'd like to do it, as said it should be a classic.
