I only managed half of my workout today (or maybe two-thirds?).
I biked for 45 minutes relatively hard and immediately (3 minutes) got onto the treadmill and ran for 30 minutes at a pace a little faster than my usual (that's only about a 9:50 mile right now) but felt pretty good about it.
However, I did not manage to finish my swim. Or start it. I didn't have the energy and I needed to get work done.
