I began with the exciting men's mountain biking - the end of the race literally had me sitting on the edge of my seat!
Then it was on to equestrian jumping.
This was New Zealander Clarke Johnstone clearing one of the jumps.
The canoe slalom finals were also great to watch. The contestants have to navigate through a series of hanging gates in river-rapids conditions.
This is harder than it sounds, and over 15,000 cheered them on.
It is great to have so much to watch while I'm immobile, but my attention span is starting to waver a bit.
I'm not used to sitting around this much!
