Pearsall Park isn't a road course. You'll climb, you'll bomb descents, and after this week's rain you'll almost certainly hit mud. Here's how to move through it — and what to carry so it doesn't break you.
Steep Pearsall hills reward quick, choppy steps over long powerful ones. Keep your feet under your hips, hands relaxed, and hike the walls — hiking a steep grade is often faster than running it. Push off the quads with hands on knees on the worst pitches.
Fight the instinct to slam the brakes. Lean slightly forward from the ankles, let gravity do the work, and let your feet turn over fast. Eyes 10–15 feet ahead — not at your shoes — so your brain can pick the line before you get there.
Dark, glossy mud = deep. Cracked or matte mud = shallow crust. Run the edges of a puddle when you can, and if you must go through, hit it straight and fast — sideways slips are how ankles roll. After heavy rain, expect the low sections of Pearsall to hold water for hours.
In Texas summer heat, thirst is a lagging indicator. Sip at every aid station (~1 mile apart), alternate water and Gatorade, and take a gel or chews every 30–40 minutes. 25K runners: eat real food at the finish-line aid before heading out for loop 2.

RD:No strollers on the 25K/10K — the singletrack is too narrow and technical. Leashed dogs are OK on the 5K only, but please start at the back.
RD:Yes — drop a labeled bag at the E-Dragon tent by 6:20am. It'll be watched until course close at 11am.
RD:Best spot is the start/finish arch — 25K runners come through between loops, and 10K/5K pass the finish once. There's also a great sightline at the aid station near Ninja Adventure Park.
RD:If you're inside 2:15 you continue. Right at it — the timer makes the call. We'd rather move you to the 10K finish than pull you off course.
