Hmm, maybe the 19km run on Sunday wasn’t such a great move. OK it was good mentally as I did it so I know I can keep going, but the right foot/ankle pain I got during the run looks like a case of plantar fasciitis. Not good as it means right now, on Thursday, 4 days after the run, walking is still on the painful side, let alone running, so my plan of a couple of 8k runs this week has gone and the half-marathon before Christmas might have to be dropped as well.
The reason for the injury? Too far too soon (a 5km jump in distance was not a good idea) and my running shoes, which are getting too old and worn out (probably still ok for shorter distances but not the longer runs).
So now it’s rest, recover and then start building up again. How frustrating but only myself to blame.
