Hey team,

I’ve recently been getting some bad cramps in my trapezius muscle ( shoulder ) while running. Only on my right side. This happens right around the 4-6 km mark and stays for the duration of my runs. Usually 10-15 km. I was hoping maybe somebody has experienced this in the past and what they did to overcome it.

Some background.

I’m an average runner. Last year for 10 k I was anywhere from 45:30-48:00 minutes but I wanted to break 45 minutes this year. I put in some good winter training and some hard work this spring and I got to my goal. Since then I’ve been pushing even harder and recently just ran a 42:50. By pushing harder I mean more training and better eating habits. I’m feeling great during these runs minus the shoulder cramp. I’ve been eating healthy. I drink a lot of water and I’m fairly stress free lol. Some of the symptoms I’ve googled suggest those as triggers. The only other thing I can think of is possibly my form. I don’t think I’ve changed anything but with the faster pace it could be something small and I’m not noticing it.

Anyone with suggestions or advice would be greatly appreciated.

Thanks again

Quinner
