I had done this one before, but yesterday on a ride with Radu, Graham, and Joey we ended up at the northern end of the Blackstone Bikeway. Not knowing where to go from there, I suggested that there was a “mountain” up ahead in Woonsocket. They were a little skeptical as to whether they wanted to climb a mountain, but I assured them, this is a “Rhode Island Mountain,” meaning not really. It was a little more difficult than I had remembered it. We turned left on to Mount St. Charles Road from Manville Road. If you come from the north on Manville, however, it extends the climb a bit. The first section if fairly gradual and not too steep. Once you take a right onto Logee Street, however, it really kicks up. The last section is probably 12 percent. I’m not posting a gradient map, because it’s all screwy, and shows spikes of 22 and 25 percent, which is definitely not right. Here’s the veloroutes map.
