Nearly 38,000 charity fundraisers and professional runners make this year's event the biggest ever!
A whopping three quarters of a million spectators turn out in London to support this iconic and special day!
After dropping my bag to the baggage truck and a last stop at the urinals, which has a very long line of runners now. I head over to the starting pens. I am in pen no1 again which is at the front.
Rather like sheep pushing into a bottle neck, without much movement we wait anxiously and I enjoy the banter and conversation around me. I can hear mentions of Boston last week and Berlin marathon in Canadian, American and thick European accents over us Brits.
Running friend Mark Jenkinson shouts from the back of the line at the top of his lungs to me. He is too far away for me to get to so it is just a cheeky smile and thumbs up to him.
After a few minutes we are all ushered into the start pen and just moments away from the mass start. the sound system seems to be having troubles and the voice over is all broken.
The miles seem to tick by nicely, through the Docks and Bermondsey as the crowds carry everyone along the road. I pass my water along to the person next to me, at each water station, until the tight groups start to seperate more so.
Then at the 9th miles, I keep hold of the next small Buxton water bottle. It is small enough to carry in my hand without feeling weighed down.
After taking another salt stick capsule with some water at the next water station, I carry the small bottle again as it is just easier than running across to try and grab one amongst everyone else.
The route heads east along towards Limehouse and Blackwall, I start to feel fatigued and overheated some, my pace is starting to drop. I try so hard to keep my pace to around 6:40min/mile and quicker, but I feel as if I have started out too fast and I cannot keep this up much longer!
I really struggle with these next few miles, at 17-20 around Isle Of Dogs before heading back on ourselves into central London. I am averaging around 7:00-7:15min/mile and the hopes of reaching a PB today have been squashed...
I take a sip of some olive oil that I always carry running, with another salt capsule. At the next water station there is a Lucozade gel hand out. I wouldn't usually take these, but I figure it is easier to have the sugar trickle now rather than rummaging for the jelly babies in my waist race pack.
Just approaching the last mile marker along the Embankment and the roaring crowds are electric. It is so loud and overwhelming...
Passing the London Eye and then Big Ben. This is it...
My low mood and disappointment of not reaching my target time are all now forgotten with the amazing sights and support for the final leg to Buckingham Palace.
I felt better at Brighton two weeks before, which is odd as it was after the SDW50. My heart was in it more so compared to today. I did feel that London was very much more congested this year and the dark cloud humid conditions really didn't help with my pacing.
I have not been training as much road so gave it my best shot today. Happy to reach a sub 3hr for the year as it was two years ago the last time.
I have not yet decided. I would enjoy to see Sunday experience it and hope that he gets a place in the ballot next year.
