Technically lastnight as I am doing almost all my riding in the evening after 10pm (young child + working from home = hard to get out during the day).
Did my normal route along the Tamagawa here in Tokyo. Started in Fussa city near Haijima station, followed downstream the northern bank of the Tamagawa to Tachikawa station area (~10km). Crossed the river into Hino city and headed upstream along the southern bank of the river. Took some detours away from the river to do some climbing, but back to the river and home. ~22km ride.
