Wow! I really got hammered today. We were supposed to run 400m x 8 at 10s above our MTT but boy it was hard. First 4 trials were ok, 5,6& 7 could barely finish it and was not able to run the last one. I just could not do it 🙂 took be 4/5 hours to get my heart rate back to normal – makes me realize how unfit I am.
