I have been thinking about the Olympics and about sports. I think it would be much more challenging if some sports were combined so that the athlete had to master several skills at once.
I have a few suggestions:
100 m Fencing
Synchronised Swim Boxing (two teams of synchronised swimmers would launch team members wearing boxing gloves at the other team to try to disturb their routine)
Synchronised Ski-jump Shooting
Triple Javelin Jump
I think I would be particularly good at 200m Rubbish Talk.
