Thomas was competing in the Longest Lap race on his return to the London Velodrome, but was disqualified before the race really got going
As the riders took up their track-standing positions in the home straight, the Welshman rolled to the top of the track and started greeting fans.
Whilst doing so he took hold of the railing around the edge of the track, something that is strictly forbidden in the race – for obvious reasons.
The Team Sky rider is popular with home crowds and this is evident when the spectators begin a cheerful mock-booing as he is asked to leave the track.
Thomas was making his competitive return to the Lee Valley Velopark in London for the time since the 2012 Olympics.
While he might have not realised exactly what was going on, his teammate Pete Kennaugh came agonisingly close to holding his track-stand shortly before the race lap, but was forced to unclip and leave the race after losing balance.
Not long after Thomas’s exit the whistle sounded and the race began. A handily timed roll from Adam Blythe placed him perfectly to ride away from the remaining riders giving him enough time for a bit of showboating towards the finish line.
