The Poudre and Great Western Trail Loop offers a varied surface, ideal for gravel biking. You'll find a mix of paved sections, particularly along the Poudre River Trail, and significant stretches of crushed gravel, especially on the Great Western Trail. The Great Western Trail portion, being a former railroad grade, is generally quite benign and relatively flat. Some routes can be up to 80% paved, while others incorporate more gravel farm roads.
This particular 69.6 km loop is rated as 'difficult' and requires very good fitness and advanced riding skills, taking over 5 hours to complete with around 250m (820 ft) of elevation gain. While parts of the Poudre Trail are flatter, the full loop incorporating the Great Western Trail presents a challenging ride. Shorter, more moderate sections of the Poudre Trail might be suitable for those with good fitness but less experience.
The best time to ride this loop is generally during the spring, summer, and fall months when the weather is mild and the trails are clear of snow and ice. Always check local weather conditions before heading out, as conditions can vary.
