Every year one of the world's most prestigious route setters (Percy Bishton, who co-owns The Climbing Works) gives the elite boulderers of the world something to get their teeth into right here in The Outdoor City.
With climbers coming from Japan, GB and right across Europe those lucky enough to grab a ticket will get to see top-level athletes in a brilliantly intimate setting.
And in true community spirit, The Climbing Works allow anyone to enter, and have plenty of fancy dress and fun competitions going on alongside.
This event is part of the Festival of the Outdoors, find out more here.
As tickets to see the Climbing Works International Festival in-person always sell out fast, we're offering an additional opportunity for spectators to be part of the action this year with the CWIF Watch Party in Sheffield Winter Garden- see more here
