Eight of us were blown along the river path to Erith last friday. The coffee at Firepower! was pretty bad and we ducked under massive shell explosions. It was mild and the sun shone for much of the time, a pleasant ride downwind. One of the ex-Arsenal ordnance piers at Woolwich is being dismantled. Lunch in Morrisons was OK. Two of the group made their own ways back, leaving the rest of us to battle back against the strengthening wind. 28 miles.
