I’m bang in the same position, I’ve done so much endurance stuff over the last 18months I’ve really neglected to the speed and track stuff, im literally plodding along and seemingly finding it impossible to get quicker. I’ve gone right back to the start, booked a 10k race and will follow a plan to try and get quicker again, i was doing around 23m 5ks and bust my balls recently to see where i was and it was 27.30, i couldn’t have gone quicker either. It was a shock
