Great ride today .. Very tight in some sections. Anyone with 780mm be aware ! Upper sections were awesome .Lower section near river had various pockets of mudd which weren't a big deal , however the tree completely blocking the blind corner wasn't any fun. If you take the easy section by the river you bypass the issues mentioned until someone can clear the tree. All and all great run in the city. Jul 15, 2018
