Quote of the Year #1: "What a great idea for a challenge and a stunning route – running fresh into the dawn across the downs was pretty special. It was a virtual challenge before every event went virtual this year due to Covid – you were ahead of the crowd – who knew?! It’s certainly provided a training focus this year when everything else seems to have been cancelled – so thank you for that." Richard Hamstead, #ultrashufflers

Quote of the Year #2: "One word: BRUTAL." Simon Allchin, The 414 Club

Entry is now closed for all attempts from 1 January to 31 December 2020.

Entry was £100 per team (and increased to £200 on 1 January 2020)...

...BUT, we've put the cost back down again, to £100 PER TEAM, with the cancellation of the London Marathon and the Oxfam Trailwalker.

Don't waste your fitness - take the Yellowhammer Challenge! (team numbers are limited).

"’s £100 a team, so a bargain!" Stuart Holloway, prospective entrant

Teams of two to four. It's not a relay. If you want a medal, you must do the whole thing.

You decide the day - and the hour - of your start - but you must finish the same day - by midnight - to get your medal!

Charitable fund-raising is NOT required (but you might as well, eh?!)

Teams are self-sufficient - but must have a support crew.

No race markers - navigation required.

No marshals - you have to look after yourselves.

No timekeepers - it's self-timed (use GPS and Strava to prove your success on the course).

See (or hear) a Yellowhammer (bird) for additional self-satisfaction.


The Yellowhammer's song is traditionally rendered as 'A little bit of bread and no-cheese.' Perfectly apt for Operation Yellowhammer.

A £1000 donation has already been made to the RSPB, to help conserve the 'red-listed' Yellowhammer.
