Lance Armstrong rides during a training session on the first rest day of the 2009 Tour de France.
Texan Lance Armstrong has brought Scottish traffic to a standstill after more than 200 cyclists answered his Twitter invitation for a casual bike ride.
The seven-time Tour de France winner issued the invitation while in Glasgow to watch Irish rockers U2 play Hampden Park later Tuesday.
Joining Armstrong on his rainy ride through the Paisley district was two-time world champion and former world record holder Graeme Obree.
Armstrong is expected to compete in the Tour of Ireland next week.
