Treadmill run. I was planning on doing 4 sets of 6 mins at 5k-10k pace w 3 min recovery jog. I felt so sick after the first interval, I wanted to throw up or pass out. I stopped and walked a little and then only did 2 more intervals and reduced the time to 4 mins for the last 2. I walked a little, then jogged to cool down. I still felt really awful for about 45 mins after this. Maybe I didn't eat enough yesterday or maybe it is the high altitude, I just hope I am not getting sick!
