.5 miles with the team. I couldn't breathe other than short fast breathes, even though we were going over 7:30 pace, and eventually I had to stop with my hands on my knees. Arm also went numb when running, had chills and shakes later in the day. I walked back to the locker room, ended up spending most of the day at the hospital, but after a lot of tests, they couldn't determine the exact problem, but of all the things they expected, they all sound very minor. Hope to run a bit on Saturday.
