You have 24-Hour to explore and run any distance you like, with the opportunity to achieve one of the toughest 100-Mile races anywhere! We start in Monrovia Canyon Park-Camp Trask. You are encouraged to come Friday and set up your base camp. Set up your tent and gear next to the Boy Scout Fort - which provides a unique and fun experience, please bring the entire family, crew, or friends – all extra support team are free and encouraged! Saturday morning the race starts. 100-mile runners go out first, then Individual and team 24-hour runners follow shortly after(100 milers start at 5am, 24-hour racers start at 8am) . The race ends Sunday, 24 hours later for team and individual, and 35-hour cutoff for 100-mile athletes(4pm). If an individual or an individual of a team achieves 75 miles during their 24-hour race, they may elect to carry on.
This race is self-supported. We encourage everyone to be festive and creative with your camp. We will have movies as well as arts and crafts for the family! There are multiple loops all leaving from base camp. Every time you head out you check in at the head table which is at the fort at Trask. You choose which loops you want to do, and how many miles you desire! There are also challenges through the 24 hours if you desire such as midnight yoga, and community service. At the end points are earned by your miles as well any extra challenges you do. You are never far from base camp and your gear/fuel/food. There will be hot food for sale at base camp! The mood is festive with lights, movies, crafts, and onesies. You may encounter bears, cats, deer, and other wildlife but they are your SISU neighborhood friendly wildlife friends, so bring your camera!

Trail and Camp
We are trail runners and love this community. SISU is very proud to offer this race at an affordable price point. Included in your registration is 3 days of camping! The Camp has suffered a lot of damage from fires and floods so this year Cabin stays are not an option. Please bring your tent, sleeping bag, etc. There is a main area where you will have access to set up your camp site. Remember this is just to sleep, we expect you out and racing all weekend! Additionally, the Fort at Camp Trask has recently been remolded and this is where our base camp will be held. Athletes are invited to come and set up tents in and around the camp. All profits will be donated directly to the restoration of the camp, so please be understanding of the years of tribulation.
Please bring your family and crew and camp for free on us! Set up a tent, use your car, just be mindful of the bears and keep your things locked up. Fires are not permitted.
