BigMud Trails (EARTH)
BigMud is the first event in the Classic Element Trail Series, themed on the element Earth. It takes place in the Meon Valley with a start and finish at Queen Elizabeth Country Park in Hampshire and uses single lap trail routes across the South Downs National Park.
The event offers three race distances:
- 16 Miles: £40
- Marathon: £52
- 50km Ultramarathon: £62
Each route includes a 518 ft climb to the summit of Butser Hill, reached twice on the course, and then follows trails and rolling hills before returning to the park. Course marking is provided, and runners are advised to download the GPX file as a backup.
Mandatory kit and services: All runners must carry at least 500 ml of fluid; hydration vests or handheld soft flasks are permitted. Appropriate clothing for changeable weather is advised. A bag drop tent will be available. Canicross entries are not accepted.
On-course support and cutoffs: Aid stations are provided at specified mile markers for each distance and include sweet and savoury snacks with vegan options, plus water and flat coke. The event supplies PH 1000 electrolyte drink and assorted energy products at aid stations. Cut off times are set for each distance.
Event items and options: Event T-shirts are available by pre-order and can be collected at Event HQ. Runners may choose to have a tree planted instead of a finishers medal through the Trees Not Tees scheme. On-course photographers and volunteers will be present.
