Probably the same as anything. Be prepared. Make sure your food/bottles are ready to go so there’s no faffing looking in bags and have some variation. 24 hours of just eating one thing will make you want to top yourself. Likewise lay out any spares, lights etc you’ll need. Lots of fresh clothing too.

Specific tips for a 24hr I can’t really help with.

– Decent pegs and straps for tying the gazebo down (screw in pegs are very good)
– Consider a ground sheet for the gazebo, keeps everything dry
– Lighting (rechargeable strip lights, etc)
– Bike stand
– Bike washing facilities

Guessing you are riding relentless at the end of the month, plenty of batteries for lights and all your riding clothes, so no matter what the weather chucks up you are covered.

Chamois cream. Loads of. You’ll chafe to buggery if it’s wet. Especially once you get grit in your shorts.

I was trying to find a way to say this but that says it better.

Basically set up with minimal comfort and nowhere to sleep (or you will).

However if you have a pit crew, then they will need comforts – they have a most unpleasant job, at least you get to ride. 🙂

My provisional kit for the ‘Puffer this year is a folding chair, an insulated box to stop my drinks freezing, and an umbrella. Last year I made the mistake of sitting in my car for a minute, next thing I knew it was a few hours later, big mistake. You feel like crap after a sleep like that, you’re better off crawling round the circuit with your bike on your back than sleeping IMO 🙂

Have a small tool box for quick repairs. You can take a big one with all your tools, but you really don’t want to be raking around in through a pile of tools when you just want to do something basic, so it’s easier to find it in the small box.

Every minute you save by not being in the pits is like being a little bit faster.

Get a foolproof way for quick battery changes.

And as richpips says DO. NOT. SLEEP

Good luck.

That’s only when I have to build another bike… 🙂

Don’t listen to the DO NOT SLEEP messages!
If you are in it to win it, then, no you can’t sleep. or go for a crap, because you’ll get beat.
A sleep is fine IF you have the willpower to get up.
Don’t get in a sleeping bag, preferably sleep in your biking gear, (good time to change into fresh stuff.)
Set an alarm for an hour or 2.
And then get up and get on your bike.

Practice by commuting to work on a pushbike if you are able.
If you can get up at 5/6am and get on a bike that you have to pick up from next to a nice warm van during the working week you can do it during a race.
