low back pain after run

hi all, i'm on wk6 completed my 2nd run yesterday, felt good throughout the run but developed low back pain on one side in the evening and woke to find it really stiff and sore today my next run is sunday, and this will be for 25 mins i really dont want to miss it - has anyone else had this - btw i do strengh/core work 2 days pw and pilates 1 day pw, my core is pretty strong and started core work 6 weeks prior to starting the c25k - any advice would be very welcome - i've really got the running bug and i'm afraid that this will set me back...

Welcome to the forum and well done on your progress.

This guide to the plan is essential reading healthunlocked.com/couchto5...

and includes advice on minimising impact, stretching after every run, hydration and strengthening exercises, all of which will help.

Weak core is often the cause but perhaps you have another issue which is being highlighted by the impact of running. If it persists then best get checked out by a physio.

Are you wearing good running shoes suitable for your gait?

Enjoy your journey.

Hi thanks for your reply, I have good running shoes but haven't had my gait checked I follow the NHS Stretch after running after each run

I'll have to wait for the pain to ease before continuing I think but I don't know what else to do to prevent it, thanks again

The guide has advice on dealing with injury.

Thank you for your advice, the problem turned out to be an inflamed sacroiliac joint which got better with ice and stretches, I only missed 2 runs....
