Know before you go
- Access points (like Zilker, Spyglass, Gus Fruh and 360/Loop 360) have limited parking and some involve steep, rocky descents.
- After heavy rain, crossings can be dangerous and parts of the trail may close. Check City of Austin updates and never cross fast-moving water.
- There's little to no drinking water on the trail. Carry your own, especially May to September.
- Watch your footing on smooth limestone when it's wet, and watch for wildlife.
Your first run here
Start from the Zilker end and run out-and-back on the flatter main trail. Walk anything steep or rocky. That's what experienced trail runners do too.
What makes it special
The Greenbelt is Austin’s classic trail: limestone ledges, big oaks and cedars, and a creek that comes and goes with the seasons. It is beautiful, popular and a real step up in difficulty from crushed granite. Take your time and enjoy it.
The right mindset
Treat your first visit as an exploration, not a workout. Walk the rocky and steep sections, take photos and turn around early. A great first outing is a 30 to 40 minute out-and-back on the flatter main trail.
A sample 40-minute workout
- Walk 5 minutes to warm up and find your footing.
- Run easy for 2 minutes, walk for 1 minute, and repeat, walking every rocky section.
- Turn around at 20 minutes, no matter where you are.
- Cool down with a slow walk, then stretch.
Terrain skills you will use
- Short, quick steps on rocks.
- Choosing the flattest line, even if it zigzags.
- Careful footing on smooth or wet limestone.
- Slowing down before descents.
- Scanning ahead for roots and loose stones.
Water, weather and closures
The creek is often dry in stretches, and there is little drinking water, so carry your own. After heavy rain, the creek can rise quickly, sections may close, and rocks and mud can be slippery. Check official City of Austin updates, and never cross fast or high water.
Busy times and parking
Popular access points get crowded on weekends and after work, and parking can be tight. Go early on weekdays for a quieter experience. Plan alternative access points, and do not block driveways or park illegally.
Trail etiquette
Stay on the trail, yield to uphill runners and hikers, keep dogs leashed where required, pick up after them and pack out everything, including gel wrappers. Keep music low.
Common mistakes
- Trying to keep a road pace. Slow down and walk when it is technical.
- Wearing road shoes with smooth soles in wet conditions.
- Starting too late on hot days.
- Not telling anyone where you are going.
Next steps
Follow the plan weeks 3 and 4 here, and consider joining a clinic, where a coach can point out the best lines and safest sections.

Conditions change. Check official City of Austin park and trail updates before you go, and never cross flooded water. Trail running carries inherent risk; run within your ability.
