Overview
You decide how far you want to run! The 3.5-mile off-road loop means your race can be 5K or even over 80K and anywhere in between. You decide how many laps you're going to do on the day within the 6-hour time limit. If you're looking to cover a marathon distance you'll need to complete 7 laps (+ a little out and back) and a half marathon will be 4 laps (and a little long at 14 miles!).
The route is along well-maintained pathways. There isn't a meter of asphalt and the pathways are mainly crushed stone or very well trodden open forest floor. Obviously being in the middle of a forest the narrower ones are covered in tree detritus and can become a bit muddy and grimy, especially when wet. On a dry day, road shoes will be perfectly acceptable, on a wet day, trail shoes may be a better bet as some parts can become a bit slippy.
Cut off
6 hours.

I had a lovely time at this event. Everyone was very friendly and I felt welcome and supported. The aid station was as good as ever and so was the flapjack! :) It is a beautiful course, well organised and a lot of fun! Kaz K
Great event and location. Well organised and friendly. Achieved my first ultra marathon. Elaine G
Beautiful course, mainly flat and a good running surface. Well organised event, friendly, great aid station and relaxed atmosphere. Hard to fault. Brian T
Everybody there was incredibly friendly, supportive and helpful. The course was so beautiful it didn't feel like running laps at all, and the pit stop in between laps had a vast range of different goodies to fuel you. So impressed, thank you!! Suzie F
Brilliantly organised, great atmosphere & camaraderie among everyone there. These events are really friendly and inclusive. A really enjoyable and memorable day. James M
Of all the events I've done, this one I enjoyed the most. Just enjoying each 5K lap and stuffing my face at the aid station in between and obviously an awesome medal. My most enjoyable 26K so far. Dean W
A lovely course through the forest. The aid stations were well stocked and all the marshalls were exceptionally friendly and supportive. This was my 11th Big Bear event and I can't fault them. Thank you, Paul and the team. Robert S
A most magical event with such a friendly, welcoming atmosphere it felt more like a big, happy family gathering. The food on offer at the aid station was of high quality and good to see wholesome stuff rather than a load of sugary rubbish! The delicious Tribe protein bars for those of us who are vegans or have allergies were especially welcome as was the fresh fruit... Marshals and officials absolutely brilliant and to put the cherry on the top, a simply gorgeous course... Highly recommended! Jim E
The event was in a beautiful location, well marked, well organised, and undulating so not too hard a route. But what made it was the friendliness of everyone involved, from race director to volunteers to the rest of the participants - everyone said hello, encouraged each other. Claire B
