Spring and fall give runners and cyclists the cleanest training window here. The scorching heat of summer has given way in fall, and the chill of winter has yet to arrive. Fort Collins Cycling Club makes summer social with dinner rides in May, June, July, and August, while runners keep to shaded Poudre River Trail miles or move workouts earlier. Northern Colorado can feel windy and bright in exposed areas, so Z2 days need a little patience. Winter changes the rhythm more than the identity. The foothills near Fort Collins stay rideable much of the winter, and runners still have paved paths when singletrack needs time.
