LOL Marcus, I'm sure Matt will be encouraging me too, so I've got to give it a go (still sounds like a bastard long way to go in 24hrs!)
It
is a bastard long way to ride a bike in 24 hours, have no doubt on that!
It is still one of the things I am most proud of on a bike and still gnaws away at me that I could have done better, so I am going to have to do it again sometime.
Even as I built towards it, my ideal target of 600km sounded outrageous. I had never ridden a 600km audax in less than about 35 hours. But it is about motivation I guess, on an audax I have 40 hours to do that, so can afford to relax a little and take my time at controls. But it still seemed impossible. But, on the day, it starts to come together and the ability to just keep going (particularly with support) is just amazing. The roads are fast and corners/junctions minimal, so you can sit in position and just get on with it.
I wish I had spent more time on the aero bars in the lead up. I ran them on my bike to 6-7 months beforehand. But I just kept in doing audax style long rides where there just isn't the opportunity to sit in position for the length of time you will start to in the 24. I should have ridden 100 mile time trials.
Beyond that, it was the most amazing experience. However as cet says, it was the single hardest thing ever. It recalibrates everything. I can never think of audax riding as particularly difficult now, there just isn't the same mental pressure as there is on the 24. You can not stop. It just goes on and on. Relentless pressure.
But, the flip side is that level of accomplishment you feel at the end. And to have beaten mattc's record would just take that on to a level I just can not even comprehend.
