Zion Traverse

You've got ideal trail running conditions locked in for the entire trip. Sunny skies with highs around 69°F and overnight lows in the mid-30s mean crisp morning starts that warm to comfortable running temps by mid-day. Light winds under 10 mph throughout the forecast window eliminate any wind chill concerns on exposed ridges.

Hydration needs are moderate — the 69°F highs won't stress you like summer Zion heat, but pack according to your distance. For routes over 15 miles, the 35°F overnight cooling means water sources should be flowing normally without freeze issues. Stream flows across the region are running 40-85% of median but stable, so creek crossings should be straightforward.

Daylight gives you nearly 12 hours of running time, with sunrise at 7:48 AM and sunset at 7:37 PM. For a 30-mile route, you'd need to maintain a 2.5 mph moving average to finish with daylight buffer — totally reasonable with these conditions. The consistent forecast means no weather-related pace pressure.

Start early to catch the cool morning temps on exposed sections, especially if you're hitting high-elevation terrain where it'll be even cooler. No storm risk means you can commit to longer routes without bailout concerns. This is textbook March running weather for southern Utah.
