Fartlek, Hills, type of run

The sun came out this morning while i was at work so not to miss such a rare event i stopped what i was doing put my running kit on and went for a run in case it only lasted a short period. The blue sky was welcome but could not disguise the blood chilling temperatures outside. I ended up doing an odd sort of run. My legs were tired from yesterdays efforts so i just ran as hard as i could uphill which there are many where i was today and then sort of bimbled on the downhill bits.

Ran 4.23 miles in 39:04 @ 9:14 min/miles pace
