Attempt at some speed

Out in the am again (only time it is feasible to run - too hot any later and I've cracked open my first holiday beer by 4.30pm each afternoon in any case).

Decided I needed to try some speed this morning.  Kept on delaying when I would actually try it.  Got to 7km on the Pinellas Trail, turned for home and decided to run back quicker.  Did 5kms under 4min km pace then almost expired with heat exhaustion.  

All up 14km in 4:14's.
