This is obviously a cycling race.  The man in front is called Adrian, he's been cycling for 2 hours now and his muscles are so sore.  But he's not going to give up because he needs the money.  Sean is the man right behind him, he's been trying to take over Adrian for quite a while now and he's anxious and a little frustrated.  It's almost towards the end of the race and Adrian speeds up.   Sean feels so thirsty and tired.
