well it was my fault. i was riding along the road and the cars infront were waiting for someone turning. i saw a dropped kerb so up i hopped onto the pavement BUT my wheel wasn't straight enough to the kerb and it didnt go up smoothly so i fell to the side, one foot unclipped but not the side i was falling on! either way, somehow i managed to keep pedalling and remain upright, i sheepishly went back onto the road behind the cars i was trying to overtake!!
clearly this isn't a good idea, and im not going to do it again!!
