I did this for the Vancouver Games. I'm an Olympic/multisport nut and for the days Olympics are on I'll be pretty glued to it. Unfortunately being London time viewing sports is going to be rather difficult. Vancouver was way better as the times sport was being shown was very similar to NZT. Thus I'm pissed I won't be watching many events live.
Anyway I love gymnastics so that is the ultimate sport for me. I'll watch Rhythmic and trampoline but my whole focus will be on the Artistic side.
I have always enjoyed swimming much more than athletics but I'll be watching athletics too. I like Diving as well but am not a big fan of synchronised swimming.
I'm less excited about track cycling as I don't agree with the changes they've made. Removing both the points race and individual pursuit sucks in my opinion (they are part of the Omnium). Of course I'll watch anyway. And I like BMX racing. Rowing seems to be New Zealand's best chance for medals and therefore it'll be a must watch.
I'm also keen to watch the equestrian and will keep an eye on the sailing and Canoeing. I don't do team sports and am not interested in wrestling, taekwondo or judo. I also don't get boxing or weightlifting.
