Pump up your tyres and dust off your costume, we’re back!

We’re here to celebrate cycling as fun, accessible and meaningful.

Inclusivity is at the heart of the Cobble Wobble— and this year, we’ve expanded the format to make it even more welcoming!

Kids on little wheeled bikes take on the final ~20 yards of the hill, riding through the same roaring crowd, with full fanfare and live commentary. Big smiles, happy kids, pure joy.

Junior Cobble Wobble - a shorter course (the last ~80 yards) for young riders on pedal bikes. Whether they conquer the hill under their own steam or need a little extra encouragement, they’ll be met with cheers and a tidal wave of crowd support to get them to the top!

For riders with limited mobility, reduced strength - or just a healthy respect for gravity (!). Riding E-bikes is a fun twist that opens the event to more people. Tern are also running a super fun competition whereby people will take turns to set the fastest time on one of their GSD bikes.

Category winners, plus the 20 fastest riders overall, will go through to the prestigious evening showdown to crown the ‘King & Queen of the Cobbles’ —the event’s overall champions.


So… Pump up your tyres and take on the cobbles. It doesn’t matter if you’re fast or slow, dressed as a hot dog, or walking after the first few yards — just get involved. Every kind of cycle is welcome, all ages can ride, and we promise you’ll have a brilliant time!

We simply couldn’t put on this amazing event without our wonderful sponsors and partners. Not only have our main sponsors helped ensure the numbers adds up, they’ve also embraced the spirit of the Cobble Wobble with real enthusiasm for everything that makes it so special.
