Frequently asked

• When is the best time of year to race gravel in the Rocky Mountains?

  The Rocky Mountain gravel season runs roughly mid-May through late September. June and September are the sweet spots — snow has cleared from the high passes and afternoon thunderstorms are less aggressive than peak July. Above 9,000 feet, anything before Memorial Day or after the first October storm is a gamble.
• Which races are good for first-time gravel riders in the Rockies?

  Look for events with a sub-50-mile option and under 4,000 ft of climbing. SBT GRVL's "Black" route, the shorter Belgian Waffle Ride distances, and most community-organized rides in Colorado's Front Range fit this profile. Avoid anything labeled "epic," "ultra," or with a route name referencing a 12,000-ft pass for your first one.
• How much does altitude actually affect race performance?

  Significantly — and more than most flatland riders expect. Above 7,000 ft, expect 10–15% reduction in sustainable power for the first 3–5 days. Plan to arrive at altitude either the day before (to race on travel-fresh legs) or 7+ days early (to start acclimatizing). The middle ground — arriving 3 days out — is the worst-case scenario physiologically.
• Do I need a gravel-specific bike or will a hardtail mountain bike work?

  Most Rocky Mountain gravel races are rideable on a gravel bike with 40–45mm tires. Routes that include sections of Continental Divide doubletrack or technical descents (Crusher in the Tushar, parts of Grand Junction Off-Road) are faster and more enjoyable on a fast hardtail. Check each event's route preview — race directors are usually explicit about minimum recommended tire width.
• How do I get to most of these races without a car at the start town?

  Honestly, you probably can't. Rocky Mountain gravel races are scattered across small mountain towns where bike-friendly transit is rare. Plan to fly into Denver, Salt Lake City, or Bozeman and rent a vehicle. A few races (notably those near Boulder and Salt Lake) are reachable by shuttle from the nearest airport, but check the event's travel page before booking flights.
