Left it til 930am to run today and set out determined to break 10mn/km. All well in first K coming in at 9 mins THEN halfway through 2nd K started to feel dizzy and sick. Tried to walk for 1 min then do a speed run but felt worse so ended up walking back home and shut down runkeeper in disgust at 2K/9.5 mins.
Lessons learned -
1) other runners in shorts and tees and I was head to toe in black Lycra! I MUST get confident and beat some skin on hot days.
2) should have at least a slice of toast before setting out
3) get out sooner on hot days - or leave it til a cool evening
