Trail Breakdown

Mile 0-3: The Warm-Up

Starting from the Temple Mountain staging area, the trail begins deceptively mellow through open desert. Don’t be fooled - this is your chance to warm up before the technical sections ahead.

Key features:

• Sandy wash crossings
• Gradual elevation gain
• Views of Temple Mountain

Mile 3-7: Rock Garden Gauntlet

This is where the Red Trail earns its expert rating. Multiple rock gardens require precise line choice and clutch control.

Technical sections include:

• Stairsteps: Series of ledges requiring momentum and commitment
• The Squeeze: Narrow passage between boulders (watch those bars!)
• Waterfall Drop: 4-foot ledge into loose rocks

Mile 7-10: Ridge Running

After conquering the rocks, you’re rewarded with spectacular ridge riding. The trail follows the spine with exposure on both sides - not for those afraid of heights.

Highlights:

• 360-degree views of the Swell
• Natural rock formations
• Photo opportunities at overlooks

Mile 10-12: Desert Descent

The final section flows through classic Utah desert terrain back to the staging area. Fast and fun, but watch for surprise rock sections.

Bike Setup Recommendations

Suspension Settings

For riders around 180 lbs on modern enduro bikes:

Fork

• Compression: 8-10 clicks from closed
• Rebound: 12-14 clicks from closed
• Air pressure: 85-95 psi

Shock

• High-speed compression: 1.5 turns from closed
• Low-speed compression: 8-10 clicks
• Rebound: Match fork speed

Tire Pressure

• Front: 12-13 psi (with heavy duty tube or TUbliss)
• Rear: 13-14 psi
• Run a trials tire rear for maximum rock traction

Essential Gear

Required

• 3L hydration minimum
• Tool kit with tire irons
• Spare tube (even with mousses)
• First aid kit
• GPS device with offline maps

Recommended

• Radiator guards (lots of tight spots)
• Handguards (mandatory for The Squeeze)
• Skid plate (rocky throughout)
• Extra clutch/brake levers

Pro Tips from Mountain Goat Sports

1. Start Early: Desert heat builds quickly. Starting by 8 AM gives you cooler temperatures for technical sections.

2. Pre-Ride Inspection: We see lots of bikes after Red Trail rides. Check your spokes, chain tension, and controls before heading out.

3. Clutch Control: This trail will cook clutches if you’re not smooth. Practice your slow-speed technical skills before attempting.

4. Buddy System: Don’t ride alone. Cell service is non-existent, and the technical nature means higher crash risk.

5. Water Strategy: Place an extra gallon at the halfway point during summer months. Dehydration is the #1 reason for DNFs.

Seasonal Considerations

Spring (Best Season)

• Ideal temperatures (60-75°F)
• Wildflowers in bloom
• Occasional rain can make rocks slippery

Summer

• Extreme heat (95-110°F)
• Start before sunrise
• Carry 4L+ of water

Fall

• Excellent conditions
• Cooler temperatures
• Busy with other riders

Winter

• Possible snow/ice on north faces
• Shorter days
• Empty trails
