Slow paced afternoon run in London 21km - fantastic weather. Taking it easy due to the calf strain 2 weeks ago now. Held up well.

Wearing running flats. This is the first year I have used these and have gradually been increasing the distance I run in these - slowly however.

For the 10 years prior to this I have worn Asics gel kyano then after a bit of achilles soreness I added orthotics. These have been fine accept they are £100+ a pair and heavy.

The change to running flats started after I read the book "born to run"

I had also gone to the launch of this book. The science behind running, and what to wear, planted a bit of a seed.  I went to the marathon medical conference the day before the London marathon and heard a Professor from Harvard give a talk about barefoot running and that sealed it. If you'd like to know get in contact.

I wont have become good enough to run a fast marathon in the running flats this year but hopefully one day. The weight saving in lighter shoes saves you 5 minutes on a marathon.
