If I recall from previous years its the one you happen to go climbing at on the day, just take your rubbish back to Outside and enjoy the bar-b-q.
Thought I'd check though and a few posts down there is...
Crag Clean Up 2014 will follow the usual format but includes a couple of new incentives to get out there and get picking:
Collect a rubbish bag from Outside Hathersage from 9.30 am (or let us know by 5th June if you’d like some posted out to you sales@outside.co.uk)
Go climb, walk, run or however you usually enjoy the hills, but allow a little time in your day for a litter pick.
Bring back your bag and hand in your haul by 6.00pm
Free litter pickers' barbecue 6.00 - 7.00pm
Screening of Wideboyz II in the Outside café 7.00 - 8.00pm (entry is free, but we'll be sending a bucket round for the British para-climbing team)
Spot prizes for the biggest haul and the longest distance travelled.
