I am very pleased with this week. It is the biggest swim volume I have done for 6 months and my 'feel' for the water, and more importantly my pace, was much improved over the week even as my arms became more fatigued. There was a reasonable amount of biking with a lot of it being on powercranks. My MCL, which stops the knee from collapsing inwards, became progressively more sore during the week. I switched to conventional cranks for the second half of the week and the soreness disappeared rapidly. 7hrs is the biggest volume of running I have done in at least a year. Whilst I have always felt the need to do more running, the nagging doubt over my stress fracture of 2008 has always held me back. Last year I carried on training when I was feeling uneasy about it and the discomfort soon went away. I think with injuries like this prolonged sensitivity serves as a protective mechanism, but to improve my running this season I need to up the volume whilst remaining mindful of what my body is telling me.
