Based on my previous running experience I am looking at the possibility of running close to 1:35 for my half marathon this weekend on Sunday 17th.

Taking a closer look at two of my last year’s half marathon times I can see that I had run negative splits on one race and positive splits in the next. Negative splits meaning that the second half of the race is faster than the first. But this may not always be the case depending on the conditions of the day and the course etc.

In February 2012 I ran my current a half marathon PB of 1:37:22. (current PB is 1:33)That time consisted of an average per Km pace of 4min 31secs. In this race my second half of the race was run much faster than the first. It was perfect conditions for running on the day of the event and everything ‘clicked’ for me.

In August 2012 I also ran another half marathon, this was in Taupo. In contrast I went out a bit too fast and slowed down significantly and finished in 1:38 which wasn’t too far off but felt different in terms of effort somehow. Arguably I was not planning to run faster and only entered this race at the last minute. It was however interesting to see the splits. The average per Km pace was roughly 4min38secs with the second half of the race being pretty slow going.

Leading up to this weekends race my goal is to try and run equal splits of 4min 29secs which will put me in with a chance of running a PB and getting close to 1:34:59. I also know that I can sustain 4min 20sec pace over 10-12k if I really push hard. It will all depend on the days conditions and how I feel. Either way I am pretty happy with my overall training so far and it’s going to come down to how I feel after the first 14kms. Then I know that I only need to run another 7kms and that is where (training) endurance and racing pace comes into play. Current weather forecast for Sunday 17th is ‘Dry with southerlies’ which can mean anything from breezes to gale force winds and or low temperatures. The only thing is to trust your training and run your best.
