This was the horrible reality I was pondering after our return from a three week holiday from South Africa. This ahead of preparation of building for Ironman Poland Gydnia. Not life threatening, this was leaving me however very uncertain about being able to prepare, let alone compete in or even finish the race.
I truly believed that my running “career” may draw to a close in the very near future. Meaning an end to any recreational running and meaning the end of any triathlon and the slow demise beginning much sooner than anticipated.
Such were my thoughts after a short 5 km run at an easy pace, which ended in tragic walking with resigned thoughts.
My “knee injury” which was a brutal stabbing ligament pain on the LHS of my right knee, made running painful. Very painful. Bringing me at times to a standstill.From the diagram below I speculate that majority of my injury to have been Pes Anserine Bursitis.

Today my run is slowly returning and the injury slowly becomes a thing of the past.
What I did try. Rest from bike, rest from running, complete rest, compression, physiotherapy with much effected area massage (time + $), various (de)stabilization exercises, ibuprofen gels, ice. Pretty much everything in the arsenal.
Ultimately the resolution has been a rudimentary static stretch that I believe is most likely lengthening the quadricep muscle group shortened through office work sitting, combined with cycling. I have seen this referred to as the Kneeling Shin Stretch.
I have added this with various others stretches such as a the Cobblers Stretch, and yoga’s Child Pose. The lion share of the stretch of my Quads resolved as above.
When I originally begun this stretch regularly as in daily I was barely able to bend my left knee, and not able to sit down fully. I can say that this has been the lion share of the correction. Toe very fair my physio was convinced my issues could be resolved through stretching. The actual specific efficacious stretching required in my experience is as above.
I hope this reading helps!
