Registration for our next round at York on the 19th June will open on the 2nd June for BHPC Members. The York Cycle Rally will also be taking place on the 18th and 19th of June. BHPC will have a stand there and as always there will be camping on site and various activities over the weekend.
Camping can be booked via the York Rally Web Site.
PLEASE NOTE: The racing at York will be on a 250m outdoor banked velodrome. If it is wet on the day we will not be allowed to use the track for obvious safety reasons. If that happens race entry fees will be refunded.

Probably also worth mentioning the traditional Saturday evening 'VV' pub ride, from the Rally to the Blacksmith's Arms at Naburn.  This is usually well-attended by people with anything that's not a traditional diamond-framed bicycle, and many BHPC members take part:

There won’t be any upright trikes on the velodrome, so that takes out 2-6 potential slow race entrants.

Yep!! We wouldn’t have enough bandages in the first aid kit for that!!
Unlikely to see many handcyclists either…

I am mithering about entering (would be my first BHPC race) with only five entries I could be a bit lonely my only suitable machine is a DF upright.

You’ll be more than welcome Aidan. Anything human powered is ok and we often have upwrongs racing with us…

Upright bike would have no problems with the velodrome, so the more the merrier.

I expect we'll have a flurry of entries nearer the deadline from the usual suspects.  With just the velodrome booked, it's unlikely to be oversubscribed.

My guess is many are waiting to see what the weather forecast says next Wednesday...

Yep.  York Rally weekend, so it's either going to be windy, pish or scorchio.  Or possibly all three.  With any luck I used up the wind on last weekend's camping trip, but that doesn't help with the risk of cancellation due to rain.

York is the same day as the London-Brighton ride, which I will do, so I won't be there Disapprove

No Jochen, but I was thinking it might be fun to ride along the coastal bike path and see you there as it's not too far from me (by car at any rate.) I'm thinking you will take about 3 hours?

Not sure what happened to my member discount (yes I  took care to log in) does it apply only during the member entry period?  (tried but member entries were closed yesterday)


Posted By: AlanGoodman
Date Posted: 09 June 2022 at 11:37am
Nope! Members should only pay £9 whenever they enter. Are you definitely a member for 2022? Have you been receiving the magazines? We’ll need to look into it…

Doesn't look like you're a member, at least not as far as the shop knows.

The shop shows your transaction for the race entry, and one previous transaction from last year for 2021 season membership...

That'll be it then! Membership runs January to December now...

Aiden are you riding your upright trike?

For the avoidance of doubt: Entry opening to non-members does not close it to members, who also have until next Thursday to enter.

(Some shop item gymnastics is required to make it work this way, which it why for the initial period it might appear that they're two separate things.)

You only see the member option if you are a current member and signed into the shop…

Reminder that registration closes tomorrow.  We currently have 10 people signed on, with many of the usual suspects conspicuously absent.  The weather forecast is currently looking dry and not too windy.

Apologies I've missed the cut-off for sign-on for York but I'd like to race if I can pls.
I cracked a rib at weekend and was waiting to do a 'test' turbo session tonight before committing - I thought the entry was open all day on Thurs, but alas not.
Let me know if OK, and what I need to do to enter. Russell Bridge, No 13 on the Nocom. O/P/U

Hopefully you'll make the bakers dozen riding no 13.

We do currently have 12 racers, so I'll dig out the Babbage-engine and add you to the list.  You'll need to email Heather to sort out the money.

No more though.  I'm going to bed, where I will undoubtedly fail to get much in the way of sleep, before travelling to the rally tomorrow.  (This is why we have a midday on the Thursday before the race deadline - gives the evening to sort out the files and write timing tags, before going incommunicado on the Friday.)

Hi
Is there a sign on time / race format for York pls?
If not can I suggest:
15mins clockwise
30mins anti-clockwise
4 lap (1km) flying-start time trial (more feasible with only 13 riders)

Big thanks to Heather and Andrew and Kim for organization and timing yesterday. Two fantastic fast races with me, the Watsons, Andrew and David all very close - tactical racing needed & sprint finishes in both races - love it! Can't wait to see David's vids of these races, and to see who actually won the photo finish in the second race between me and David.

Thanks Russ, Its always good to get some input into race organisation. Apparently it is an (unwritten) rule that you always ride velodromes anti-clockwise which is why we did all races that way. A 4 lap flying start might have been better than the fastest lap of 3 but we can try that next time.

I believe some velodromes (fairly sure London is, not sure about York) are actually asymmetric and thus specifically designed to be ridden counter-clockwise only.

I'm sure I read a few years ago that Manchester was making people ride clockwise in order to even out the wear on the boards, but I strongly suspect it to have been an April Fool or similar joke, jape or gag.

Results!  We haz them!

http://www.bhpc.org.uk/Data/Sites/1/media/events/events22/04york/index.html" rel="nofollow - http://www.bhpc.org.uk/Data/Sites/1/media/events/events22/04york/index.html

Observant readers will notice that the third race appears as both a three-lap time trial and a one-lap time trial.  This is because we used the software in time-trial-timing mode (manually without the RFID system, because reasons) to record that event.  It doesn't have a concept of best-of-n, so I've hand-crafted a fake one-lap time trial using people's best lap times in order to display and further process the data.  Really observant readers will notice that some of the times are different.  This is because we were also recording times with a Mk 1 stopwatch and clipboard, and I've taken the faster of the two best times for each rider.

Now, you're probably thinking 'Never mind all that bistromathics, what about the photo finish between Russell and David in the final race?'

Well, it was certainly close.  Too close for the RFID data to be of any use.  Fortunately, we now have CrossMgrVideo.  Unfortunately, we have a 30fps Logitech webcam, which was plonked on the table behind the computer in the timing tent, and not a high-framerate industrial camera on a tripod aimed perpendicular to the finish line...







It's clear from the surrounding images that Russell was overtaking David as they crossed the line, but with the parallax error, that's too close to call.  So I've done the only reasonable thing and given them both the same finishing time!

And, since the software surprised me by not choking on Natalya appearing twice in the same event (she had a second attempt at the best-of-three with her e-assist battery removed, for multitrack points SCIENCE), I've quickly and efficiently updated the championship tables without any hacking:

Great job, Kim. I was wondering how we were going to score the 3-lapper and your solution seems perfect.

The photo-finish looks like it's down to where their cranks were as they crossed the line so a dead-heat is fair, if the software allows.

(Remembers the time in Roskilde when Dave Richards' body crossed the finish line marginally before that of Johnny FOREIGN but had mounted his transponder on the trailing edge of his tail fairing while the Cunning Continental had his mounted in the vicinity of his front wheel. The rotter.)

I knew it was close, but not that close!

I completely f'd up the end of that race - I found myself on the front of the line with three whole laps to go to the checkered flag and I thought sod it - I'll hold the inside line and they'll just have to come past me the long way. Three laps later I was miraculously still leading, but what there was not was a chequered flag but a sodding bell....aaaaaargh.....1 more lap at full tilt with a lunatic Frenchman bouncing away on the outside resulted in a new all-time maximum heart rate of 185.

I'll take a draw...unless David's camera shows otherwise...


Posted By: Kim
Date Posted: 20 June 2022 at 11:41pm
Which by some freaky coincidence is about what my heart rate reached as I failed to hold on to your wheel about a third of the way through.  I thought it reached 190, but it turns out that was during the sprint finish with Jack (alas, no photo needed for that one).

Well the PLAN, such as it was, was to swap the lead a couple of times then for you (probably) to surge past, fully refreshed, into an uncatchable attack. I was as surprised as anyone when you insisted on hanging on heroically in front. Makes for good TV though Clap.

Spoke too soon.  I just noticed it wasn't showing the tie between Russell and David in the points table.  This is because CrossMgr (rather unfairly, IMHO) doesn't have a concept of ties, so I check for them during the final re-write of the finish positions in the merge-o-matic.  Which is an infrequently-invoked line of code that I'd failed to update when CrossMgr changed to outputting the Excel data as numeric fields, rather than strings.

Anyway, now fixed.

Hi Kim
I've been wondering why my e-trike which has a defunct motor seemed so slow compared to my other trikes in roll down tests and a long search of the internet has revealed that the rear hub motor itself has drag equivalent to a pair of extra tyres, so in equivalent Natalya was riding a five wheeled trike. So well done her.

I was wondering if I should remove my non functioning motor as I have a regular rear wheel that I'm not using. Seems like it should make it easier on hills as the motor is not working anyway. It's only the very low gearing that makes it possible to use.  

All the best.
Roy
