So I finally did it! I must admit it isn't really for me and I am unlikely to go again.
There was a total of 511 people! I found the start very difficult as you are so hemmed in by people and it felt weird running so closely in a group. However once everyone spreads out a bit it was much better.
I can't see how the timings are very accurate in terms of the people at the front of the starting line will get a big head start! I was pretty much at the back! However my timing was pretty good. 33 minutes for the 5k and it said - for my age group (I'm 40) I came in 15th so that was interesting.
Haha as I was going around I was pretending in my head that we was running from a zombie apocalypse so when I passed someone I could think they would be zombie bait instead of me! It was interesting seeing so many different styles of running and all shapes, sizes and types of people! I liked seeing children running with their parents. They somehow make it look so effortless! Even if they get tired with the duration I notice they soon recover enough to zoom again!
So very interesting. But I prefer the headspace - and just space - of running solo me thinks!
