Time to wake up the fast twitch muscles and try to get my body used to handling lactic acid. :) Coach Mark's instructions were to do a 5K time trial in under 24 minutes, so that's what I did! 2.5km warm up down to the SMU track, 5km around the track in 23:13, 400m walk to cool down and a 2.5km jog back home.

Average Heart Rate: 180! Max heart rate: 187!

However, I did NOT puke or even really feel like it, which I think means our interval session last week was beneficial.
