I got my chat with the Physio this morning. Very useful advice. PF can take a long time to resolve itself. Luckily I have a long time. Great pamphlet for reference: https://www.cht.nhs.uk/patient-leaflet-repository/...
Booth House, Flush Houses, Digley. Foot a little sore to start but getting better as the run progressed. Obviously just talking to a Physio on the phone is effective :)
