A Messed Up Short Tempo Run ~~~~~

Really cross with myself!  I seem to mess up just about everything I do lately.  Out late and it was hot even though I had a shaded road to run on.  I looked at the Garmin and thought the distance said 2.6km and I'd run too far; instead it was 1.6km!  How could I be so bloody stupid?  Started Garmin again but I was so annoyed at having spoilt the session I stopped after another 0.5km.

Supposed to be a ST run of 2.5km

 

500m splits :   3:44; 3:51;  3:50;  3:51

TE   1.9  =  Minor
