So for those who remember just over 2 months ago I did the first run of week 2 and the following morning struggled to even walk down the stairs.
The exercises the Bupa triage physio gave me to do didn't really improve matters so after a week he referred me to see an actual physiotherapist.
After a couple of painful sessions of physiotherapy, and a number of weeks doing the exercises she's been telling me to do I can actually run again
Re-did week 1 runs over a couple of weeks and then this past week completed week 2 with no real issues!
Very pleased Looking forward to seeing how I handle run 1 of week 3 tomorrow now!
