VOLUNTEERS:
The event literally wouldn't happen without the support of our wonderful volunteers. We hope you can join us next year.

London 100 has been created by a team of dedicated ultramarathon enthusiasts. We believed that London deserved its own 100km ultramarathon. The event will showcase the wonderful sights of the capital and to make ultras more accessible.

By volunteering, you'll be helping this event establish and grow into what we hope will become a bucket-list challenge for all ultramarathoners. 

You can VOLUNTEER in the following ways:
Volunteer and Run - enter the event with one of our HALF PRICE places for volunteers. For example, you may volunteer between 6am and 10am to help registration, and then start your London 100 challenge at 11am. Or you may want to run first, and then come back later to help the later finishers across the line. 
 
Volunteer recruitment for London 100 (2026) will open soon.
