CHOOSE YOUR CHALLENGE

Run the Light is a lap-based event on a scenic out and back path along Lake Travis. Burn off the Christmas feast with movement, fresh air, and the Hill Country sky. Walk, jog, run, rest, refuel. Your effort is yours to manage.

🌅 Endurance Run | Morning Start Window

Start any time between 7:30 AM – 12:00 PM

Run as many laps as you choose before sunset. Ideal for runners targeting 4–8 hours of movement. Maximum time on the course before the light fades.

🌇 Endurance Run | Afternoon Start Window

Start any time between 1:00 PM – 5:30 PM

A focused effort as the day winds down. Ideal for runners targeting 1–4 hours of movement. Feel the urgency as the sun lowers toward the horizon.

10K 1:00 PM START

 A set-distance option with the same solstice spirit. Features beautiful lake views throughout on smooth paved surfaces. Run or ruck option available.

5K 2:00 PM START

Perfect for those new to trail running or wanting a shorter celebration of the light. Ideal for PR attempts and first-time racers.

Participant numbers are capped to meet City of Austin requirements.

WHY RUN THE LIGHT?

The day after Christmas. The days are shortest. The light is returning. Burn off the feast. Celebrate the season.

🌞

Challenge the Daylight

No cutoffs, no eliminations, no overnight miles. Just you, the trail, and the low winter sun. When the light is gone, the day and the run end together.

🧠

Reflective Experience

The day after Christmas at the lake. As the sun arcs low across the Hill Country sky, every lap becomes more intentional. A peaceful way to close out the holiday.

🏃

Your Pace, Your Day

Walk, jog, run, rest, refuel. Your day is yours to manage. Whether you're chasing maximum distance or simply want to spend a full day outdoors in motion, Run the Light meets you where you are.

WHO THIS IS FOR

Experienced Endurance Runners

A unique seasonal challenge without overnight running. Test your endurance against the natural constraint of available sunlight.

First-Time Endurance Athletes

No pressure of cutoffs or eliminations. Run as much or as little as the light allows. A welcoming entry point to longer efforts.

Anyone Seeking Meaning

Start a new holiday tradition. Celebrate the return of the light with intentional movement the day after Christmas.

The week of the shortest day. Longest effort.
