THE DREAM
A loop course through the Goodan Ranch Sycamore Canyon Preserve east of San Diego.
Picture the course in advance
and find the pace that fits you.
Streets lined with cheers, runners all around.
You'll be part of that scene.
Take it slow with the finish still in you,
and meet the city all over again.
From the joy of finishing to the tough moments — read what runners wrote themselves.
“Running hurt about the same as walking so I just kept running.”At the Sycamore Canyon 100K, they used ice to stay cool over eight laps in heat reaching 40°C. They kept running through the final night section and finished within their 16-hour goal.
We translated a short line from each public race report and summarized the experience. Finish times are as stated by the author, and past editions may differ from this year's weather and operations.

Pick up your bib, check your wave.
So on race morning, you can just run.
Goodman Ranch Sycamore Canyon Preserve, Poway, CA (preserve straddles the Poway/Lakeside area).
Parking is NOT allowed in the immediate start/finish area — runners/spectators must park along the road outside and may need to walk up to half a mile in.
No public transit;
rural preserve, car access only.
Same as start — loop course finishing at Goodman Ranch Sycamore Canyon Preserve.
All distances (100K, 50K, Half Marathon) use the same loop start/finish area;
hard cutoff requires runners out of the park shortly after 10PM.
None mentioned.
No transit card is required at the trailhead;
Sycamore Canyon in Poway, California is a county-park venue reached by car, not served by San Diego transit.
For the broader San Diego trip, MTS/NCTD use the PRONTO reloadable card or app (adult one-way fare $2.50 with a 2-hour free transfer window, $2 card fee),
purchasable at trolley stations, transit stores, and via the PRONTO app.
Your start time, fuel and bag drop.
Know them ahead and the run feels easier.
Sycamore Canyon registers through UltraSignup, with three events — the 100K, 50K, and half marathon —
and both the 100K and 50K can also be run as a 4-person relay in addition to solo entry.
A notable feature is that solo entry in the 100K requires prior experience completing a distance of at least 50K,
and an early-start option is available for runners expected to take longer to finish.
Start times are staggered by event.
Based on the previous year, the 100K early start was at 4:30 AM, the regular 100K start at 5:00 AM,
the 100K/50K relay and solo 50K at 6:00 AM, and the half marathon at 7:00 AM.
The race has a cutoff of 10:00 PM, after which runners must leave the park,
so 100K participants in particular need to manage their pace with this time limit in mind.
The course uses a loop course within the Goodan Ranch Sycamore Canyon Preserve east of San Diego.
Times are local to Poway. Check the latest official information before the race.
