In this scene, there are several bicyclists.  The facial expression of the man in the foreground seems to be of relief, as if during the race, he was having difficulty and was probably losing the bike race.  The fans in the background are very into the race.  Everybody is probably feeling very anxious as the race is drawing to an end.  I think that the man in the foreground, who is also the lead in this bike race, will win the bike race.  The crowd will probably go crazy when he crosses the finish line.
