Sometimes a run comes along that defies logic, a run that makes all the hard work . the early mornings, double up days, long runs, time in the pain box, thresholds etc. ; all seem so worthwhile. This years Perth half was one such a run. My half pb stood at 1:16:24 set in 2013 and it was a time I was happy with and one I thought I would never better.  Boom ! After a great training block I surprised my myself and broke 1:16 for the first and probably last time. 1:15:55 according to the photo below. Still smiling. Big head wind which made for a good negative split. One of those runs where everything comes together, at my age a rare treat.

A half is a good distance, not too long to disrupt training but long enough to be a good test. Normally set off at 10k pace and try and hang on for as long as possible. On this run hung on until the end.
