It had to happen. I hadn't had an injury since starting c25k in July 2016. Since my 10k last Thursday I have had groin pain even on walking. I did a slow, painful 2.5k on Tuesday (don't know how I managed it).
Today I went out for a walk along one of my running routes. I went dressed for running in case I felt like breaking into a trot. I did try this a few times but it hurt so much I had to stop straight away. Walked about 3k with a slight limp.
I have a 10k event in just over 2 weeks and don't know if I'll be able to do it. I have booked 2 sports massages between now and then, so those may help. I feel despondent and am realising just how much running has been contributing to my wellbeing. I remember tripping over a tree root towards the end of last week's 10k, it was the closest I've come to falling during a run. Maybe that's what did it.
