100K Solo & Team Area

A dedicated area will be provided for all 100K solo runners and 100K teams, giving you a clearly defined space to return to throughout the event for your kit, nutrition, crew support and race essentials.

This area is specifically reserved for the 100K categories because of the longer time they will spend on course and the repeated support they may need across multiple laps.

Runners taking part in the 50K, Marathon, Half Marathon and 10K will also have access to appropriate event support and resupply points elsewhere within the event village.

Every distance at the Chanctonbury Chase presents its own challenge, and all runners will receive the support appropriate to their event.

Camping at The Chanctonbury Chase

Make a weekend of it and stay overnight in our dedicated camping area within the event village, set on the grounds of Wiston Estate.

Arrive the day before, check out the course, soak up the pre-race atmosphere and enjoy a night under the stars before taking on the challenge the next morning.

Choose from an 8-person pre-pitched tent for teams and groups, or a 2-person tent for solo runners or pairs. Your tent will be ready and waiting, so there’s no setup and no early-morning travel — just wake up around 100ft from the start line and get race-ready.

Pre-pitched tents can be added during checkout.
