new record

today wear the NB stability new shoes and heart rate meter, run the canal route normally, was overtaken by 3 on last 500metres, but my heart rate was at 93% since 1km, i was probably dying theoretically. Finished in 18min 49 sec, fastest ever 2.4km lately but could have been faster but was adamant not to re overtake the 2 of them in front as it not so nice. Walk back 3km more, to warm down and seem heart remain at 140-145 beats per min, or 80%. Finished 1.5hr session and reach home totally flat, and my 2 children are waiting for me for soccer game. Almost died, we went 30 min, we finished with a sprint up staircase 6th floor. 2hr later, finally finished. Heart beat was 110-120 during rest 2hr later, maybe another sign of exertion and poor fitness .....
