Frequently Asked Questions

What skill level do I need to race The Original Growler?

The Growler is not a beginner-friendly event. You'll need advanced technical skills to navigate challenging terrain, rocky sections, and fast-flowing singletrack on granite trails. This is a backcountry endurance race, so riders must also possess the fitness to sustain 4–8 hours on the bike. Honestly assess your abilities before registering—if you're unsure, you might not be ready.

What makes the Hartman Rocks trail system so challenging?

Hartman Rocks features nearly 100% singletrack with rugged granite terrain, technical rock gardens, and fast-flowing sections that demand focus and precision. The high-desert elevation in the Gunnison basin adds another layer of challenge—expect thin air, dramatic elevation changes, and stunning but unforgiving mountain vistas. These trails are maintained and built by the community, and racing them funds future trail development.

How do I prepare for the elevation and high-altitude racing conditions?

Gunnison sits at elevation, so arrive a day or two early if possible to acclimatize. Train on technical terrain and focus on your pacing strategy—rushing at altitude will drain you fast. Bring extra hydration, electrolytes, and calories; your body works harder in thin air. Check the event website for specific elevation profiles and trail maps to dial in your preparation.

What distance options are available, and how long will my race take?

The Growler offers multiple race formats designed for different endurance levels and ambitions. Depending on your chosen distance and pace, expect to be on the bike for 4 to 8 hours. Check the event website for the latest race categories, distance breakdowns, and elevation profiles so you can pick the format that matches your fitness and goals.

What gear and bike setup do I need for these technical granite trails?

You'll want a hardtail or full-suspension mountain bike with good traction and geometry suited for technical, rocky terrain. Bring a reliable drivetrain, tubeless tires with appropriate tread for granite grip, and don't skimp on brakes—you'll need strong stopping power on fast descents. Protect yourself with a quality helmet, gloves, and body armor if you're comfortable. The granite is unforgiving, so prepare accordingly.

Is there parking, camping, and spectator access at Hartman Rocks?

Hartman Rocks is a public recreation area with parking and amenities, but the Growler is a backcountry endurance race—spectating is limited and trails are remote. Check the event website for parking details, camping options in the Gunnison area, and any designated spectator zones. This is very much a rider-focused event in true Colorado backcountry.

Why is The Growler a grass-roots community event, and how does my entry fee help?

For over 17 years, The Original Growler has raised funds to build, maintain, and expand the very trails you'll be racing on at Hartman Rocks. This isn't a corporate event—it's powered by mountain bikers committed to growing world-class singletrack in the Gunnison basin. Every entry directly supports trail development, so you're investing in the future of the sport and your local riding community.
