Training - Day 31

6 months ago I used to start running at 12 kmph and build upwards for 30 minutes. Since then I have been running longer and slower and so today's task of 6 x 400m at 12 kmph was absolute hell. I quickly ran out of breath and my legs killed - especially my calfs. My stride got so heavy that several times people right across the gym turned to make sure that the rampaging elephant that they heard didn't mow them down. Oh the shame of it!! The worry for me is that next wednesday I have to run 14 lots of 400m at this pace - how the blooming hell am I going to do that!!!!
