I went out on Tuesday night for a run that was supposed to be another heart rate running experiment. 7.3km later and I completed what could best be called a fartlek run, with some hefty pace variations and not a stick of heart rate running (except for looking at it occasionally on my watch and cringing). Actually I enjoyed myself, and finished the session with a smile on my face. During the past run sit down and run watch upload I reflected that I have some hard thinking to do before the Cardiff half marathon.
Basically having made a foot placement switch off of my heels, and changing shoes for once and for all, I am firmly in an in-between state where I could happily run a 5k or 10k this way but have no idea how a 21k would look. I would like to run the distance and find out but I know that that way madness lies. Whereas I was not patient with the heart rate running this week I am going to have to be with my half marathon progress - only finding out if I can do it in low profile shoes, on my midfoot, running with a different running form on the actual day. I am more than a little bit scared of the challenge, as realistically I need at least another 12 months or more to work through the changes and make them a comfortable 'default' setting.
The event in 6 weeks or so is rapidly looking like an day out running rather than an attempt at any sort of time.
