The Monserate Endurance Test is a choose-your-own-adventure style endurance event designed for everyone. Whether you’re chasing big mileage, testing your mental grit, or just looking for a fun excuse to spend a full day on the trails, this event lets you go at your own pace and see what you’re capable of. With permission from the Fallbrook Land Conservancy (FLC) the course is a 4-mile loop on FLC's Monserate Mountain Preserve, with 1,300 feet of elevation gain per loop. You decide how many loops you take on. Walk it, hike it, run it, shuffle it. Every loop completed is a win. There’s one fully stocked aid station at the bottom of every loop, so you’re never far from fuel, water, and encouragement. Come hang out between loops, cheer others on, and soak in the community vibe. This is a challenging course, no doubt, but it’s also meant to be fun, supportive, and welcoming. No pressure, no cutoffs per loop, no expectations beyond showing up and giving it what you’ve got. Whether you complete one loop or ten, you’re part of the day. Come get after it. Come test yourself. Come spend a full day moving through the hills with good people and great energy.

Event Options:

• 12-Hour Solo – How many loops can you complete from sunrise to sunset?
• 12-Hour Team – Tackle the course together or split up however you want. Teammates can run at the same time or separately, with the goal of accumulating as many total loops as possible as a team over 12 hours.
• 6-Hour Solo – All the challenge, half the time.
