First of all, there’s no reason why Olympians should be amateurs – the original ancient Greek athletes weren’t.
Get rid of most of the running. All those distances, 100m, 200m, 400m, 800m, 1600m, 5km, 10km, Marathon… Good grief. Swimming is the same, but with different strokes too – there must be more medals on offer than competitors.
Never understood why there’s Judo and wrestling, should just be wrestling – learn it in a judo school if you like.
Taekwondo? Do me a lemon, it was embarrassing.
BMX racing actually seems a good fit, equipment is pretty simple and it combines explosive sprinting with guts, aggression, and technique.
And bring back pankration.
