Did the local tour on Sunday, 140 km. The weather was great and around 2000 cyclists showed up. I rode in a huge bunch, which made it an easy Sunday ride. Only the last 20 km, or so, was racing. The start was just beside the Helsinki velodrome. For the first 11 km all 2000 riders went slowly behind a lead car. I rode with a bunch going for an average speed of 32 km/h. The finish was actually at the velodrome, which was cool.
Some previous postings about the velodrome (1, 2, 3, 4, 5, 6, 7, 8).
