I have previously mentioned that I now have a Garmin Forerunner 620. Having never used a sports watch before, and being a bit analytical by nature, I am mesmerised with all the stats provided.
So for me to have perfect form and or technique in running, I pretty much need to hit the purple bands on each of the graphs for pace, steps per minute, VO2 and Ground Contact Time (GCT). I have managed to get purple on every graph bar one so far, indicating a pretty good technique. However on Ground Contact time I land more in blue than purple. I then noticed something – when I run in shoes, my New balance zero drop Minimus, I get a blue GCT, but when I run BAREFOOT, I get the elusive purple target area.
A week ago I did an awesome 5km sprint, backed up the next day with an awful half marathon “race”, of which I got muscle fatigue from the second km. So have used the week up having sports massages, feeling sorry for myself, taking a bit of a break and just working on sprint training.
On Tuesday we had sprint training usually on the pavement which is perfect for me. Except this time we moved onto grass. It was early in the morning and very very frosty. The grass was actually covered in a fine layer of ice, which crunched and broke leaving my perfect little footprints behind as I ran along this. Freezing cold barefoot ice crunching was not my idea of a fun start to the day. My feet it seemed were also not impressed, as for the first time in a year of barefoot running, my soles have reacted, which as I have only done those two sprints in the last week, and my feet were physically aching from Tuesday, it is like the thick layer of my skin on my foot sole is trying to peel off. Most annoying, and has left me with achy tired feet all week. Either that or perhaps I am getting a tad worn out, although I have cut back to doing only about 60km a week at the moment.
