Cobblemonster

It’s London’s original and best Urbosportive! Or, in plainer terms, it’s a bike ride around a route marked out for you across some challenging terrain, right here in the capital, inspired by the iconic Paris-Roubaix.

We will start from 08:30am at upCYCLE LDN departing for cobbles and climbs aplenty before finishing at Herne Hill Velodrome, SE24 9HE for a victory lap, followed by food, drinks and men’s Paris-Roubaix live on TV.

We can’t wait to see you all again on Sunday 12th April 2026 at upCYCLE LDN.

Registration is now closed – drop us an email at info@cobblemonster.com

Start
upCYCLE LDN, Unit 1 & 2, Fairfax House, Overton Road, London, SW9 7JR from 08:30-11am
Finish
Herne Hill Velodrome, 104 Burbage Road, London, SE24 9HE (track open from 1-3pm)

The route will depart from upCYCLE Ldn and descend into the melee of the West End, blasting across some early secteurs of the smoke’s Victorian pave before tucking into the east end and its myriad lanes of snaking cobbled nadgery.

We then cross the river to start a series of LBCs (Lung Bursting Climbs) which increase in frequency before the descent from Crystal Palace to the finish at Herne Hill Velodrome, where you can finish  a flying lap, in homage to Paris-Roubaix (helmets are mandatory for the velodrome lap, sorry!).

The route is designed for riders of all abilities, all bikes welcome, and encompasses a number of London Overground-enabled bail out points for those that suffer with mechanical or physiological events.

For some this will be the biggest bike ride they’ve ever taken on, for others it may seem like a gentle spin.

We guarantee all riders will know they have ridden their bikes!

Entry is ‘free’ but we recommend a donation to our new official charity partner, Wheels for Wellbeing.

Our guideline donation is £15 and this has remained the same since the very first event in 2009.

If you’re taking part it will help a lot if you donate upfront, it is much easier than giving us cash on the day!

The generosity of our punters has meant over £55,000 has been raised since 2009. In the words of the dearly departed Brixton Cycles Workers Cooperative, we salute you!

We are changing things up… our target charity for 2026 is Wheels for Wellbeing and all profits from the event go their way.

You can donate directly here – please do Gift Aid if you can – our suggested donation remains £15 as per previous editions of Cobblemonster.

Since becoming a registered charity in 2007 (no. 1120905), Wheels for Wellbeing have worked with thousands of disabled children and adults who face barriers to taking part in any physical activity.

Informed by life-changing personal experience of disabled trustees, staff and volunteers, Wheels for Wellbeing are determined to show that anyone can enjoy cycling, given the right equipment, support and environment.

Cobblemonster previously supported the Evelina Children’s Hospital Charity from 2009 – 2024, with over £55,000 raised across previous editions to support their vital work and they remain close to the hearts of everyone involved with Cobblemonster.
