⏵ Course guide · Memorial Park trail race
Trail Racing Over Texas brings the first official trail race to Houston's Memorial Park, natural-surface singletrack through the Bayou Wilds trail system with distances from a 5K up to a 50 mile. I will walk you through the course first, then give you a pacing and fueling plan for a loop-based, beginner-friendly ultra format, plus free tools to dial in your own numbers.
These facts come from the official RunSignup event page for the race. Check the current year details, cutoffs, and aid stations before you commit. Race logistics change year to year.
The race runs on the blue, purple, and orange trails of the Bayou Wilds trail system inside Memorial Park, a natural-surface singletrack network that the organizers say will make you forget you are in the middle of the city.
Expect natural-surface trail throughout: dirt, roots, and occasional sand, with minimal pavement and just one controlled road crossing at South Picnic Lane. There is no published elevation figure, but Houston terrain is inherently flat, so the demand here is sustained time on uneven natural footing rather than climbing.
The format is loop-based out of a central start/finish hub at the Cullen Running Trails Center, with three aid stations, Main at the start/finish, Crestwood / Memorial Trailhead, and Picnic Loop, spaced roughly every 4 to 5 miles. That gives you frequent, predictable access to aid and your own drop bags, which the organizers specifically pitch as a plus for first-time ultra runners.
Memorial Park is one of the largest urban parks in the country, and Houston Ultra Trail is described as the first official trail race held there. Combined with staggered start times (6:00 AM for the 50 mile down through 8:30 AM for the 5K) designed to reduce congestion, the race is built to feel calm and organized on a trail system that has not hosted a race like this before.
With minimal elevation and a loop-based, aid-dense format, this is a course where sustained effort management matters more than climbing strategy.
Natural-surface singletrack with roots and sand costs more energy per mile than firm road or gravel, even without real elevation change. A grade-adjusted pace target still helps here, mostly by keeping you honest that flat does not mean fast on technical natural surface.
With aid roughly every 4 to 5 miles, treat each station as a natural checkpoint. A race-time prediction built off your real fitness gives you a baseline finish estimate for the 50K or 50 mile, which you can then sanity-check against how you are actually feeling at each aid stop.

Mid-February in Houston is typically mild, but Gulf Coast humidity is always worth planning for, even outside the peak summer heat.
Aim for roughly 60 to 90 grams of carbohydrate per hour on the 50 mile and 50K. With aid roughly every 4 to 5 miles across the Main, Crestwood/Memorial Trailhead, and Picnic Loop stations, you have frequent chances to stay on schedule rather than carrying large reserves.
Sodium in the 300 to 500 mg per liter range covers most runners on a typical mild Houston February day, pushing toward 700 mg per liter if humidity runs high. Track how you are feeling at each of the three aid stops and adjust rather than locking in one number for the whole race.

Summit Line reads your real training, builds a plan for natural-surface trail over distance, and rehearses your fueling so race day is something you execute, not guess at.
It is billed as an approachable entry into ultra distance rather than a technical mountain test. The course runs on natural-surface singletrack through Memorial Park's Bayou Wilds trail system, dirt, roots, and some sand, with minimal pavement and only one controlled road crossing. There is no published elevation figure, but Houston's terrain is flat by nature, so the challenge here is sustained time on rooty, natural-surface trail rather than climbing.
The race runs on the blue, purple, and orange trails of the Bayou Wilds system inside Memorial Park, described by the organizers as flowing loops on natural-surface singletrack with minimal pavement. There is one controlled road crossing at South Picnic Lane, and aid stations sit roughly every 4 to 5 miles: a Main station at the start/finish, one at Crestwood / Memorial Trailhead, and one on the Picnic Loop. It is a loop-based, central-hub format, which the organizers pitch as easy access to aid and drop bags for first-time ultra runners.
Mid-February in Houston usually runs mild, though humidity is always a factor near the Gulf Coast. Aim for roughly 60 to 90 grams of carbohydrate per hour on the 50 mile and 50K, and sodium in the 300 to 700 mg per liter range. With aid roughly every 4 to 5 miles across three stations, you have frequent access to reset your intake, which the organizers specifically call out as a benefit for first-time ultra runners.
That is exactly how Trail Racing Over Texas positions it. The Houston Marathon runs in mid-January, and Houston Ultra Trail follows about a month later in mid-February, pitched as a natural next step for marathoners who want to try trail running and go beyond marathon distance for the first time. If you are coming off marathon training, the loop-based format and frequent aid make the 50K a reasonable ultra debut, building on fitness you already have.
The lineup runs from a 5K up to a 50 mile: 50 mile, 50K, 25K, 10K, 5K, and a free Kids K for participants 12 and under. Start times are staggered through the morning (6:00 AM for the 50 mile down to 8:30 AM for the 5K) specifically to reduce congestion on the shared trail system.
Yes, this looks like one of the more beginner-friendly ultra formats in Texas by design. It is the first official trail race at Memorial Park, built around a central loop hub with frequent aid, minimal technical difficulty, and organizers explicitly marketing it toward marathoners taking their first step into ultra distance. As with any brand-new event, go in with a flexible plan since there is no prior edition to reference for pacing benchmarks.
