Lately, I've been working on finding new running routes that are either near my house or along my way to/from work. Last week, I stopped in Waterford and hopped onto the Old Champlain Canal Path. When I had initially read about the tail, I thought that it was 3 miles in length (6 miles total). It ended up being closer to 1.5 in one direction so 3 miles total. It's possible that I could have crossed at the lock and there may be a trail on that side, but I was only looking to do 3 miles anyway, so the distance worked for me.
Since we've had almost NO rain this year, the path was dry, but I could see it being a wet mess during a normal winter/ spring. It's a nice flat run and knowing that it's about a 3 mile loop, I plan to stop there again on my way home from work to knock out a few miles.
