Del Puerto Canyon

48.8KM
↑ 0501-0750m


This route is a subset of the Patterson/Early Bird Road Race, traditionally the first race of the Northern California road racing season, promoted by the legendary Velo Promo. This version starts well outside of Patterson, where the real-life race begins, shortening the route to under 50 km. It opens with 20 km of gradual uphill, typically 2%, but with brief sections slightly steeper, as the road winds along the bottom of the canyon. But here things get more interesting… From 20 km to 22 km, the grade gradually increases, a warning of what’s to come: a 2.5 km at an average 9.3%, with sections reaching 12%, finally relenting just a short distance from the turn-around. But while the major climbing is done, in a way, the race is just beginning, because after 4 km of rapid descending, a chance for races both climbing and descending to see the gaps to riders behind or ahead, there’s still a 20 km run back to the finish line. The downward grade here, typically 2%, isn’t enough to let up on the pedals. Rather it’s just enough to make drafting a huge benefit, and so groups MUST work together, and a solo rider off the front is going to face an extreme challenge to hold that gap all the way to the end. The road is ever-twisting, rarely flat, so with groups shattering on the steep climb, then hammering on the seemingly endless run from the base of the main descent back to the finish, memorable racing is guaranteed.

    This course makes for really tough racing. I was pleased with how well the road flowed, both on the steep climb, and with the seemingly endless turns on the gradual descent back to the finish. Only downside is the handling of out-and-backs. This course has the out and back split, and the return road suddenly appears around 1 km from the top, while the upward road disappears at the same point on the descent. The alternate would have been to have the out and back roads coincide, but it’s not clear if the bots would stay on the safe side of the road in this circumstance. The cattle guards and canyon slopes of the real road are missing, but as Magic Roads go with its limited scenery (as I write this), I thought it worked exceptionally well.
