Hard Riddles

At the recent downhill mountain bike race, four entrants entered the challenging slalom event.

• Alan came first.
• The entrant wearing number 2 wore red, whereas John didn’t wear yellow.
• The loser wore blue and Steve wore number 1.
• Kev beat Steve and the person who came second wore number 3.
• The entrant in yellow beat the entrant in green.
• Only one of the entrants wore the same number as their final position.

Can you determine who finished where, the number and colour they wore?
