Slightly off topic, but does anyone know how control timings work for PBP?
Even simple calculations for closing times for the first few controls at the 15km/h minimum speed quickly fall apart.
Am I overlooking something here, or does ACP just fudge the control times for some reason?
I too find the lack of information on minimum speeds and control closing times a bit surprising. I don't plan to be riding/stopping/sleeping at anywhere near the minimum average speed but I'd still like to know before I pick up my brevet card.
After mining info from the RUSA site I have used these formulae in my spreadsheet:
=N$1+(K4*43.5/(24*611))
[where N$1 is start time, K4 = cumulative distance (on the way out), 43.5 hours is how long the 90 hour starts have got to get to Brest (@611km), and 24 = no of hours in the day]
and for closing times on the way back:
=P$10+((K14-611)*46.5/(24*607))
[where P$10 is the closing time at Brest (start + 43.5 hours), (K14-611) = cumulative distance (from Brest), 46.5 hours is how long the 90 hour starts have got to get back from Brest, 607km is the distance back, and 24 = no of hours in the day]
Through curiosity I've knocked up a sheet based on the distances on the offical info sheet and your formulae with my pre-reg start time.
https://1drv.ms/x/s!AlB7bV6RdTovht1fHb_dPUexamhu6QThe most important bit of information for me on that is that based on what I learnt about my sleep needs on BGB (that I can keep going till around Midnight the following night on an evening start)
Is that to have any chance of making Brest before sleeping I'll need to average 20kmh.
More realistically I'll get to Carhaix.... Bugger.
However on BGB I got up around 10am, had an easyish day on trains then got a few mins sleep in the back garden of the scout hut in a bivvy bag but with not enough layers to really sleep, where as for PBP my thoughts are to try and sleep till just before check out time at midday which I'm perfectly capable of... and hope that lets me stay awake that bit longer.
hm...
Don't really have an evening start planned to try that out on though.
