Richmond Park 3-lap Challenge 2009

hungryjim

Hi all, first time poster here.

Not particularly pleased with my time of 64:17 set on the weekend, but thought I would post it up here anyway to make sure I try harder next time! I think I started too slowly as each lap was faster than the one before. Definitely keen to break the hour barrier as soon as possible. Might be able to get out for another go tomorrow...

Yes, the pedestrian gates can be used by bikes, and you still get commuters going through all hours day and night (other than when the cull is on of course) The deer and bunnies do start coming onto the road / side of the road to eat the closely cropped grass though, so watch out for them.

Nice one, cheers. Will try to avoid bike/wildlife incidents!

I'd be quite chuffed with that as a first attempt! Although perhaps if I lost 30kgs I'd be closer to your time....

No problem with gates (Roehampton Gate)

Intended to due a 3 a lapper last night. Got their at 8pm Weds night and the park was all but deserted. The conditions were not conducive for a flyer so did 1 anti lap and saw how appalling my time was so limped home.

Hmmm.... you never know what can happen so I say you should always finish your laps especially as you had made the effort to get to the park in the first place - a fair old trek for you. The last time I was in the park dong a 3 lapper I was 1 1/2 minutes down just over half way through the second lap, as a result of some vehicular obstructions. That gave me the impetus I needed to post the fastest single lap I have ever done and I managed it on my 3rd lap of three - I improved my 3 lap best by only 10 seconds or so, but was really chuffed as I actually managed to improve my time despite the worse conditions. Its not all about the time (though it is nice to see yourself go up the board) - its about the sustained effort, see Toks' post about the 'Hour of Power' which was the reason (and a great one) for the original thread

Fairly breezy this morning and despite one idiot in a Ford Focus who seemed not to be able to find the indicators, my fastest yet. Then attempted to do a couple of quick climbs and realised very quickly that I had shot my bolt. Right, so next target is 58.

For interest, apart from the wind, the conditions yesterday were amazing, I can't remember seeing such a combination of high temperature and low pressure for a long time. The air density right now is almost 4% greater than it was late yesterday afternoon. You go faster with less dense air because it provides less drag, this is why you typically can't go anywhere near as fast in winter.

Interesting Tarmac.
So how wide a range of air density can there be in the park with weather still conducive to cycling (eg high pressure at 0 degrees vs low pressure at 25 degrees)? And then how much difference (speed/time) could that make to a typical person on a standard road bike averaging 25mph?

We were just leaving at 8pm that day (after 4 pretty slow laps) and it wasn't pleasant!

I'd agree with Felgen though - we didn't beat any PBs, but glad we slogged it out.

colmcq2

it was perfect conditions last night. Got PB one lap of 16.11 and that was 45 seconds off my last one! If there's another evening like this, I can see sub 50 no worries.

Certainly I've seen 1.5C at a pressure of 1028 for a density of 1.30 in December, whereas the other day it was 1.17.

This page seems to be saying that the power required at a given speed is roughly linearly related to the air density:
http://www.analyticcycling.com/ForcesAi ... _Page.html

So if someone can do 3 laps at 300W at a density of 1.17, they would need to output 333W to do the same time at a density of 1.30. I reckon this equates to over 30 seconds a lap.

At the last club 10 of the season this year, pretty much everyone did their fastest time of the year, and I worked out that the air density that evening was only 1.197, whereas the week before it was 1.22.

So if someone can do 3 laps at 300W at a density of 1.17, they would need to output 333W to do the same time at a density of 1.30. I reckon this equates to over 30 seconds a lap.

At the last club 10 of the season this year, pretty much everyone did their fastest time of the year, and I worked out that the air density that evening was only 1.197, whereas the week before it was 1.22.

Interesting thread (and going a bit off-topic, I apologise). I did a 50 mile TT on one of the fastest courses in the country on Monday in misty weather and the air density according to that site was 1.20793. Still, the course record was broken and many people set PBs, granted most of the fastest times came from the later starts when the mist had gone. (Winning time was 1:40:50, course was P885).

So I wonder how much density really matters? On a TT bike, aero obviously trumps everything else, but how does that explain a wet dense day producing so many good times vs a dry day on the same course?

1.20793 is actually a pretty good air density, but I'd say wind is a bigger factor.

On my two best 3 lap times for the park, I've started around 7:30am, and the temperature is rising pretty quickly at that time. On both occasions I've got faster each lap with no increase in power output, and I can only think that is due to the air getting less dense as the temperature increases.

Very windy but then I think this is probably normal. I haven't been there many times but it is always windy. Got slowed down several times by traffic but I am guessing this is normal too.

Rode it on my road bike with no aero aids.

Went out this morning in pretty good conditions, lots of cyclists and Deer! Took 3 minutes off my time so pleased with that. Ride of the Falling Leaves in a months time.

rockymountainteam

aahhhh that explains it!
i have just moved to london from a land of mountainbiking and have been consoling myself by plodding around the park on my road bike, a lot of people seem to be taking things very seriously around the lap and i've been 'sat on' while cruising many times, i thought it was just a roadie/mtb thing?
now i see it, timed laps, all i know is i'm lapping at about 19mins steady/tempo, i generally ride clockwise as i think the views are better and it feels more worthwhile, cant wait to get out and lay down a time.
i'm a loooonngggg way off form and former fitness but this seems like a challenge.
i would be interested in hooking up with a chaingang too, so far i've not ventured very far from the park and it's making me a little lazy.
im the mtb'er in the teamrockymountain/kcap gear - i'm attached but exiled so it's free you see!

You're not allowed to sit on to get a time! No drafting allowed!

rockymountainteam

woah jibberjim... thats my point, i have been 'sat on', not 'sitting on'!
it can only have been those in the 19's per lap so 57's for 3 laps, 'they' mostly drop off after a few minutes, but one particular rouleur did come around (to his credit i supose) but after 30 seconds started flapping his elbows like we were in the break at the ronde or something?!
amusing at the time, i had no idea there was a race on!

I wasn't meaning you! I was meaning the guys sitting on! Of course, if they're going to cheat to get on the list, they could just invent a time

For your info -


Road closures. September will see some disruption to Park roads. The Park will be closed to all road traffic on Sunday 13th September for the entire day to allow annual London Duathlon to be staged. Road repairs will also be undertaken in September. Crack and pothole repairs will be undertaken in the week 7th-11th September which will require single lane traffic with stop/go boards for short periods of time. The in the week 14th-18th September some stretches of road will be closed (1 stretch at a time) to allow new surface dressing to be applied. They will be closed for no more than 1 day. Plans are all susceptible to change depending on weather etc but we trust you appreciate the need to improve the badly degraded roads.

Does this now mean that all the old times will now be null and void :?: :idea:

Surely with a nice new smooth surface out times will be faster


Just hope they are not putting in any speed bumps :shock:

I dont think its going to be a nice smooth surface! Its going to be the loose gravel sprayed with tar - rough, especially until the cars pack it down a bit, and then it might improve. I reckon it could slow things down. Pretty much like Box Hill a few months back until it was all swept.

it's very busy though should smooth it, in no time, I'm always rather perplexed as to why they have such good roads, I mean it's a park not a road yet they have some of if not the best bits of tarmac in london....

B*gger :x

What you mean Box Hill has been resurfaced this year?? Looks like it has been left to ruin for years :shock:

The side that's not the Zig Zag through the village got resurfaced, not the Zig Zag itself - which I think is not a council adopted road, so they won't fix it...

I think it's just because there are no residential properties on it, so it doesn't get constantly dug up for work on pipes/cables, hence it stays in reasonable condition. The lack of access for heavy vehicles will also limit wear.

not that but why they have these smooth roads, they could be made of hasher harder wearing, slabs say or a gravel/chippings bed, but they chose to have a smooth tarmac road though.

Oh, I see, I dunno. I saw some of their work today, and I'm not sure it is going to improve the roads for cyclists. They looked to be just patching up strips at the edge, like the dreadful section from Ham to Kingston which bumps you about all over the place and forces you to ride almost in the middle of the road if you want a smooth ride.

The good news is the wind has finally changed direction, and there should be some stormingly fast times to be had. I would have done a PB by about a minute today, but I had to go out in the afternoon rather than the evening, so was held up a lot plus I had to bump across the grass to a path along the side to get past the closed section. Was still only 30 seconds off my best time, and I reckon I lost at least that much on the last lap alone.

Indeedy... from my ride through the park this morning not much evidence of any billiard table smooth tarmac any time soon I am afraid. However - good call on the weather and wind front. I did notice a small headwind on the way into London today, so that means a light easterly and favourable conditions - surely time to have a pop at the 3 lap challenge, but I only have the training/commuting wheels on the bike today, so I guess a go at the weekend might be in order.
