In answer to your question yes.

Yes 1500 ft ascent each way which also means descents as well, <10mph on the way up, >30mph on the way down

Simples!

But if you are assuming 50% at 10mph and 50% at 30mph your average would be well below 20mph due to the fact 3/4 of your journey time would be at 10mph

In fact, assume a hyperthetical 10mile journey. To travel this at 20mph average you need to finish it in 30min. If you do the first half (5 miles) at 10mph it will take you 30minutes, leaving you 0 minutes left to finish the journey.

Think i've got that right... or maybe i should go back to bed.

Unless ITB's route was, say, 10miles up and 10miles down, in which case the downhill leg 'qualifies' but is not terribly impressive - an entirely freewheeled TT?. Actually, where could you do an entirely gravity powered 10mile TT other than the Alps/Pyrenees/etc.?

You just need a short sharp steep climb to start - say 1 mile (eg, for the Southern softies, something quick and painless like Ditchling Beacon) and the remaining 9 a nice easy run down with a good tail wind! Of course, the return trip would be rather slower......

Actually, my commute isn't entirely unlike that. I think it takes about 35 minutes to do the 9.5 miles but there are a few long gradual climbs on the way in (and 2 stiff ones) and the MTB isn't that fast.

Ditchling? Quick and painless? Very funny....

Remember it's grim up north

That it is.....living in a shoebox in the middle of the road etc
Ditchling would be quite good downhill though (though there is another climb on the run into Brighton after it, there's some really good downhills in town).

Somebody needs to come up with a 10 mile route and then we can have a commuting forum leaderboard, I vote Richmond Park for the Londoners (its not THAT hilly). Here's the official tt course:

http://www.cyclingtimetrials.co.uk/Link ... d&tabid=36

I reckon if you started and finished at Robin Hood gate it'd be more or less 10 miles exactly.

I might get down there on Saturday, running tomorrow and Sunday so due a day of "cross" training.

Is that the same richmond park that has a 20mph speed limit?

Jesus, you must have had no fun in your childhood...

Have you ever got your bike over 33mph? What road did you do that on?

in all fairness Richmond park has the 20mph limit on bicycles.. the general roads do not.

Cant be seen to be advocating breaking the law now can we?

Erm, well that'd be on a national speed limit road (y'know, outside london and everything)
Why 33 anyway?

Just remembered a distant thread about the police stopping bikes for speeding in RP, that's all, wouldn't want anyone to get caught.

(AFAIK the speed limit applies to cycles in RP, but not necessarily outside it since the speedlimit is enforced by a bylaw, or something like that)

yes and no, in RP the 20mph limit does apply to bikes out of the park 30mph limits don't.

this said still is the 3 lap challange etc.

My lungs have an 18mph limit

Any thoughts on an alternative for non londoners

I suggest that we use a recognised local club 'out and back' or circuit course.

bigmat

Obviously I should have mentioned the challenge is to hold your speed at exactly 20mph for the full 10 miles. :roll:

Any better ideas for 10 miles of uninterrupted cycling with a relative lack of traffic through idyllic scenery in central London would be much appreciated...

DonDaddyD

You are allowed to be 10% over the speed limit so 33mph in a 30mph zone, 77mph on the motorway etc. Or so I've been told. It could be argued 22mph in Richmond Park....

But, hang on a second.

On a public road, any public road, be that 30 - 40mph road, 20mph side roads and national speed limit roads those speed limits don't apply to bicycles?

Also, yes I am fully aware that Richmond Park is a 20mph zone, ALL of us know this. Kinda spoils the fun bringing it up, hence the comment.

I didn't hence the question mark at the end of the sentence, which I admit was poorly constructed.

PS, you're not allowed to be 10% over the speed limit, it's just they probably won't prosecute you for it.
If you drive at speed limit + 10% all the time, you're forgetting that the reason they don't prosecute you for it is, AFAIK, that your speedo may be 10% out so it would be unreasonable to do so.
Consequently, if your speedo happens to under-read, you will be actually doing speed limit + 10% + speedo error, which may put you into trouble.

Similarly there may be people who are unaware that RP is different, which is why I brought it up - not to spoil anyone's fun, but just so's they don't get a nasty suprise.

I did it in about 9 minutes on my MTB - it's nice . Seriously, something like that with nine miles of descent following should make a 30 minute 10 mile a doddle. 1 mile uphill in 9 minutes, 9 Miles downhill in 21 minutes - less than 27 mph.

P.S - it's true. It is grim oop north.

Problem is finding the road to do it on, not really an option in London, even in RP you get slowed by junctions and traffic. There are a couple of great roads near where I grew up that are good for this but not quite long enough. I've cycled them as part of longer rides but never timed a 10 miler specifically. If the wind is with you then on one of them you'd smash 30 minutes with ease - in fact I'm pretty confident I did on this ride, the whole moving average was over 20 and that includes a short sharp hill at the start and end as well as a rather fiddly lane at the end. Looking at the HR I wasn't exactly hammering either although I had to stop twice to let tractors and a combine pass. Problem with this part of the world is that you may get a great tailwind in one direction but as much of the ride is on flat marshland you're going to get a b1tch of a headwind at some point!

Regents Park inner circle.... although you'd have to do about 15laps. Best you're gonna get in Central London

roger_merriman

RP has lots of narrow interest groups most of whom don't much care for each other.

*devils advocate*

last year there was some TT's in the park, don't want to spoil it for others.

*devils advocate*

this said the 3 lap challenge hasn't as far as i'm aware though I expect it doesn't go down well in some places.

FWIW you wont get stopped for doing 81-82 on a motorway... most of the time
