Outstanding ride, was a pleasure to meet you afterwards Jeff 8)

Matt the Tester

didn't you do it too danowat??

Well done, Jeff

steady rider, Dan was marshalling.

danowat

No, in my first season, I thought it was a stretch too far!, and after seeing the state of some riders at the finish, I don't think I want to do it!.

There were so many top class rides throughout the field, everyone did amazingly well, and I was in awe for most of the day, seeing these riders banging in lap, after lap for 12hr solid.

If I've got the maths right, that puts Jeff (narrowly) into 3rd place (26.978mph) in the BBAR - nice one! 8)

We are not worthy!

Final lap before being moved onto the finishing circuit, about 9hrs in 8)

Matt the Tester

I stand corrected

Feel like a zombie today but it was worth it I did have an inkling that it would be possible after last week's 50, but so much can go wrong in a 12 that you can never get ahead of yourself.

If I can string two brain cells together I might sort out a blog.

I still can't believe it.

danowat

It was actually the missus on camera duty yesterday, I was busy marshalling!!!

Jeff Jones

Aha - give me a name and I'll correct

Pokerface

Well no wonder he went so fast. That bike isn't UCI legal!


Nevertheless - Holy F**K that is one hell of a ride!! Well done Jeff. An inspiration to us amateur TTers!!

rozzer32

Sorry Jeff but I'm afraid Pokerface is correct, that Shiv is not UCI legal.

Sorry but you'll have to repeat your effort on a legal bike

Well done Jeff! Top effort!

gattocattivo

Well done, that's incredible

danowat

CTT aren't bound by UCI regs, so its legal in respect of a CTT record

Jeff Jones

Who needs the UCI for amateur cycling? Under CTT rules you can still ride a Lotus, like wot Boardman used.

Now where's that steamroller? It should be quite close as it's been repeatedly running me over today.

Very well done Jeff. On a serious note, do you think you would have been slower (I know 'slower' is a relative term here) on a UCI bike..? In other words, would it have mattered..?

It's hard to say and not that important as the UCI don't govern UK time trialling. I suspect the difference is small and quite possibly dependent on wind direction. Some bikes are better in crosswinds, while others perform better in straight head/tailwind situations.

I'd like to see independent wind tunnel and real world data before making a call though.

Amazing!!

You must be one seriously fit and efficient guy!

Pross

Brilliant ride - well done Jeff.

Sadly, my understanding is the UCI rules will apply in Scotland next year

Frankly ridiculous for Amateur events :evil:

Anyway, enough of my moaning, Jeff, well done, that is some achievement 8)

Omar Little

Well done!

Very impressive

bexslack

Well done again Mr Jones.

Are you able to explain how you've suddenly morphed into a superhuman monster on a bike in the last 2 weeks? Exactly what variables have you tweaked?!

Yours expectantly,

R

Jeff Jones

Aha I have to remain a bit cagey on that one (don't worry, it's all above board).

Reducing any form of resistance is crucial - I'm sure you're well aware of this. Drag and rolling resistance are the big ones in TTing and I've done a fair bit of work in that dept, but - wait for it as this will sound like the poorest excuse in the bike rider's lame excuse book - I recently discovered that the baseplate underneath the nosecone of the bike was rubbing slightly against the front wheel after one of the bolts had come loose. It took me a couple of months to notice that because I only got creaking noises when I put weight on the bars, not when I spun the front wheel. Embarrassing! I tightened it before the BDCA 50 then put loctite on the bolt before the 12 last weekend.

That might not have been a massive improvement but every bit helps.

Well spotted, then, Jeff.
I made a similar observation a little while ago... I built up a new Cervelo S2 frame using parts from another bike. The tyres where 25mm Krylions, and after riding for a little while the front would naturally generate a little heat, expad a bit, then rub on the underside of the fork crown! Now back to 23mm tyres :oops:

MatthewBulmer

Truely outstanding effort Jeff. You're obviously in the form of your life. Once (if!) you recover, have you any targets left for the rest of the year?

Tom BB

Fine ride Jeff......you should have a bash at the 24 hour record now......if you could repeat your 305 miles for the first 12 hours, then you'd 'only' have to do 235 miles in the second 12 hours to be challenging

How much did you manage to refuel as you went? Total energy expenditure for going that fast for that long must be huge. Do you have any gadget data for calories used or similar?

My computer ran out of memory a bit before the finish, so I don't know how many calories exactly, but it was definitely over 10,000. That's more than a kilo of body fat in half a day although somehow I don't think this weight loss method will take off among the dieting crowd.

I kept eating/drinking at regular 15-30min intervals. Not sure how many calories I consumed on the ride, maybe 2000? I wasn't counting, just trying to eat. Given you can store ~2000 cals worth of glycogen then it's a matter of riding at just the right rate so you burn everything by the finish. When I got to the last timekeeper where I could stop (310 miles) I was only about half a mile from the HQ. But I was so spent that I just stopped there and then.

24hour: no, never! The 12 is enough. It's a tremendous achievement but it can take your mind to some dark places on the way.

As for the rest of this year, it'd be nice to win the BBAR but if that doesn't happen I'll still be over the moon with how my season's gone. I think/hope there's more to come next year too.
