Woke with nasty achilles pain - depressing. Maybe it was the running flats last night? The felt much better at the time.
Had some acupuncture - painful, but much better after 5 mins or so. Did some light stretching of the calf.
It's my first day of annual leave - gardening and working on computer for work!
Decided to persist with the flat running shoes - it was the best run for a long time. A bit nervous about doing 4 times this in 3 weeks time. There will have to be a fair bit of walking. Could all this supportive foot ware be contributing?
