Please check the answers below before contacting the event.
Friday registration is the standard collection time and we ask all runners to collect their race number then wherever possible.
Round the Rock is organised by a very small team. Race morning is focused on mandatory kit checks, safety briefings and getting three races started on time. Large numbers of race-day collections place significant pressure on our volunteers and can delay the event.
Race-day collection is therefore available by prior arrangement only, typically for runners travelling to Jersey from overseas or those with exceptional circumstances. Please email us before race weekend if you need to make alternative arrangements.
Yes. A representative may collect your number during Friday registration.
A change to a shorter distance may be possible if places are available.
If the shorter distance is full, a change may still be possible depending on the number of people waiting for places and the overall entry position. It cannot be guaranteed.
Please email paul@trailmonkeyjersey.com as early as possible. Do not simply arrive at or start a different distance without receiving confirmation from the event team.

No. The event is solo and self-supported. Runners may use official checkpoint supplies and their own carried items or drop bag.
No. Round the Rock is a cupless event. Carry a reusable cup, bottle or suitable drinking vessel.
