running 25:43 [3] 2.5 mi (10:17 / mi)
Ran out along the ridge trying to put some effort into the hills. Going alright, but my heart was giving me trouble and I had to stop for 30 seconds to let it settle. went as far as Delph Lane then just jogged back on the level path.
Hoping it is just a temporary blip, maybe caused by losing half a night's sleep on thursday/friday because of work.
