Distance: 51 miles and 1800 feet of elevation gain (barometric)
We start at Encanto Park in Duarte which is a few miles east of the metric start. We start by riding south on the San Gabriel River to the Santa Fe Dam and ride the rim of the dam. Once off the dam, we quickly pick up the full and metric century routes on their trip east through the San Gabriel Valley all the way out to Upland. The trip out rides long stretches on Arrow Hwy and Bonita Ave. In Upland we turn north and ride a long grade up to lunch near the 210 Freeway. After lunch we turn back west for our return. The return parallels the trip out, but along a slightly more northerly route which generally follows or rides on Foothill Blvd. In Duarte, this half century leaves the other routes for a short trip back to the start. As you can see by the profile, the route is a gentle up-grade to lunch (and a little beyond). The final 2 – 3 miles up to lunch (at mile 31) is a noticeable climb, but not too steep. Most of the return is a gentle downgrade.
