Well, I ran the Cathay Pacific Auckland Half Marathon this morning.
I’ve been looking forward to this event as it is my first race of 2009 and also my second half marathon. I’ve also been really worried about my pace lately. As you may know I’ve been doing low heart rate training and my training pace has gotten really slow. I’ve tried to run a bit faster of the last few weeks but it just hasn’t really happened. This event was the test of if it works or not. I figured if I’m slower than the previous half marathon then it doesn’t work or at least it doesn’t work the way I’ve been doing it. Although if I managed to PR…well then it would depend on by how much. For the record my first HM time was 1:59:04. How did I do this time? Well read on.
This event is a bit odd in that you have to guess your finishing time when you enter. They then give you a custom start time and the idea is that everyone finishes at about the same time. I must admit I was a bit dubious about this as I pictured horrific congestion at the end but that never really eventuated.
I left home with my Dad at about 7:45 and he set off with the 8AM starters. Yes, I do live close to the start! I hung around for a while and then set off with the 8:30 starters. I was supposed to start with the 8:35 starters as I’d been optimistic and put down 1:55:00 as my predicted finish time but while I was waiting I started to think that that might be a bit unrealistic and I’d try and do the same time as last time.
The 8AM start wave was reasonably small – maybe about 50 odd people. I made sure I was up front as there were a lot of 11K walkers starting with us (there was an 11K event on as well) and I didn’t want to get held up.
I made a point of taking it easy for the first two kilometers as I’ve always gone out too fast in past events but it turned out that they were my second and third fastest kilometers of the race so I guess I still went out too fast.
The first 5K was very comfortable. One of my goals was to chase down my dad who had started off 30 minutes before me but I saw him coming back (there was an out and back section to start) as I was heading out and I knew it would take a miracle for me to catch him.
The next 5K wasn’t too bad. The sun had come out by this time and the temperatures were rising. I think the humidity level was 89% as well so conditions were good but by no means ideal. At about the 9K mark we hit the first of the two hills and I didn’t find it too bad. I think the fact that I’ve been training on that hill meant that I was not afraid of it so that was good.
I struggled after the hill however. KMs 10 – 15 were hard mentally. I hit that patch where you start to question why you run races for time and whatnot. Having said that my times weren’t suffering too badly so we’ll just leave that there.
I’d arranged to meet my wife at a certain point (about 17.5 km in) for photos and all of a sudden I realised I was almost there and there was no way she’d be there! So I called and changed our rendezvous point. My mum, wife and daughter cheered me on:

And I must admit it was a real boost having them there. About 2 km later at the 19.5 km mark I had another great surprise when I spotted my cousin’s family. They’d come to cheer my dad and I on and it was very special to see them. My cousin’s husband told me that my dad had just gone through so I felt a burst of energy shoot through me and I sprinted off to chase him down.
I never caught him but I did manage to smash my old PR. My time was 1:52:25. An improvement of 6:39! My aim had been to hit 1:55:00 so beating that was an incredible feeling. I guess the low heart rate stuff works!
Interestingly I figure I could go a lot harder if I look at my heart rate stats. I averaged 159 bpm but my max was 166 bpm. That is nowhere near my max heart rate so I probably could have pushed it a bit more. I think I pretty much maintained the same effort throughout the race. I even even-splitted which is a first for me.
Here’s my route map:

I’ll have some more photos later in the week as the Marathon Photos folks were out in force today.
For those of you interested in the low HR stuff, Chris, sent me a great link that has some very useful information in it.
