CO9 to Hoosier Pass

The tour is approximately 25 kilometers (15.5 miles) long and is estimated to take around 1 hour and 45 minutes of active cycling time. This duration can vary based on your fitness level, the direction you choose, and how often you stop to enjoy the views.

The route is considered difficult overall. From Breckenridge, the initial seven miles are relatively easy with gentle grades (2-3%). However, the last three miles before the summit steepen significantly, reaching grades of up to 8%. While this section is challenging, the climb from Breckenridge is often described as moderate and can be suitable for beginners who are prepared for the final steep push, especially since the road generally has a decent shoulder. The high elevation can also make breathing more challenging.

From Breckenridge, the first seven miles are gentler, passing through a more developed valley, with the significant climb concentrated in the last three miles. From the Alma/Fairplay side, a bike path runs parallel to the road from Fairplay to Alma, and the road from Alma to the summit has fewer turns. The majority of the climbing from Alma also occurs in the last three miles, with steeper gradients at the bottom of this section. The scenery also differs, with the Alma side offering a more remote valley feel.

The terrain varies significantly. The initial seven miles from Breckenridge feature straight roads and gentle grades through a developed valley. The final three miles before the summit involve switchbacks and steeper grades. The scenery transforms dramatically in these last miles, offering spectacular views of Quandary Peak and impressive mountain vistas. From the summit, you'll find gorgeous views looking south over Alma, and a spectacular sight of Mount Bross and Mount Lincoln to the west. The pass itself is a natural division between the Tenmile Range and the Mosquito Range.

Absolutely. The most significant landmark is Hoosier Pass itself, which sits directly on the Continental Divide and is the highest point on the TransAmerica Bike Trail. As you approach the summit from Breckenridge, you'll get spectacular views of Quandary Peak. From the pass, the views south over Alma and west towards Mount Bross and Mount Lincoln are particularly stunning.

The pass is generally open year-round, but the best time for cycling is typically from late spring through early fall (roughly May to October) when the weather is milder and the roads are clear of snow.

You can typically find parking in the towns at either end of the route, such as Breckenridge or Alma. From Breckenridge, you would start cycling south on CO9. From Alma, you would head north on CO9 towards the pass. Specific parking lots may vary, so it's advisable to check local town resources for public parking options.

No, there are no specific permits or entrance fees required to cycle the CO9 to Hoosier Pass route. It is a public highway (State Highway 9).

This route is primarily a road cycling experience along State Highway 9. While dogs are generally allowed in vehicles on the pass, cycling with a dog directly on the road can be challenging due to traffic and the nature of road cycling. If you plan to bring a dog, ensure they are safely secured in a bike trailer or carrier, and always follow local leash laws if you stop at viewpoints or trailheads.

Given the high elevation and potential for rapidly changing weather, it's crucial to bring layers of clothing, including cold and wet weather gear. Hydration is key, so carry plenty of water. Snacks for energy, a bike repair kit, and a fully charged phone are also recommended. Be aware that cell service can be unreliable in certain parts of the pass.
