In reply to stp:
It's a deliberate clash. We decide many years ago that it'd be good to make it a bumper weekend with plenty going on in Sheffield. This has now grown into an actual thing - The Outdoor Weekender. From a ShAFF perspective we've tried to programme the mix of climbing films across the whole weekend so that it's possible to fit both events in. We're also talking to Ofo Bikes tomorrow and hoping to be able to make sure that there are a good supply of bikes at both venues so that it's easy to travel between.
