Re: [RUSA] question on super randonneur series -- lighting thoughts
Bill Bryant
About rando-lighting, FWIW, many years ago, I did a simple roll-down test with my rando-bike. The test route is one mile of gentle downslope, no uphills, no braking or turns, and it is protected by thick forest from the wind. As I recall, coasting speed w/o pedaling was about 12-15 mph. I did three runs each of a regular front hub, a SON 28 switched off, and a SON 28 with a Edelux (first gen.) lamp turned on. Both wheels had identical rims, spoke count, and tires, and the same psi in the tires. I kept my body posture the same for all the runs. Also, I am a big guy, well over 200 pounds, and over six feet tall. (A smaller rider would likely be affected more by hub drag, but possibly faster overall aerodynamically?)
Anyhoo, I timed all the runs, with the regular hub a tiny bit faster than the SON hub switched off, and a few seconds faster than with it switched on. Then I simulated a PBP plan using my two PBP finishes for time in the saddle, rolling speed, rest stops, etc. With an evening start for the 90-hr group, my conclusion was that by using battery lights (no drag) and daytime running of the SON hub, and nighttime running with the lamp turned on (between food stops), I might have earned an extra 30-minutes of rest time for that loooong fourth night at PBP for the 90-hr riders. Experience has shown that most people, especially myself, would readily sell their soul to the devil for a 30-minute nap late in the event.
So, if I go to PBP again, I might yet use the SON/Edelux (second gen.) set-up because I don’t like messing about with hauling and changing batteries, but I would think long and hard about moving over to battery lights. I really like the simplicity of a dyno hub system and have used it for many years. For a 600k and one night on the road, I don’t think the very slight drag is a factor, but on the 1200k events where too little sleep becomes a real concern, I can readily see both sides of the equipment selection question.
(And one minor advantage to the battery system is that in case a new front wheel must be bought during the ride from a control parking lot damage or a crash that leave the rider relatively ok but the front wheel damaged, then getting a new replacement is very easy—not so with a dyno hub wheel. I’ve been to PBP eight times, twice as a rider, six as a helper and I’ve seen this scenario play out several times and it is not idle speculation.)
Anyway, good luck with your SR series, and the PBP ride if it happens.

Hi Hoyt,
Good luck on your search. As with most things rando, it's a matter of tradeoffs. I personally use battery powered devices now with 10,000 mAh batteries as backup power sources. These batteries are inexpensive and small, making them easy to carry and have extras in a drop bag already charged. I have a generator hub but no longer use it because the power "it" creates is actually coming from the rider. This is true whether you are powering something, or just riding along. This will manifest itself in one of 2 ways, depending on how you want to quantize it.
1) For the equivalent power generated by the rider - the rider will be slower.
2) For the same speed generated by the rider - the rider will need to generate more power.
This is simple physics because there is no such thing as a free lunch. There are numerous sources on the web quantizing this metric. Here is one such source.
https://www.cyclingabout.com/how-much-do-hub-dynamos-really-slow-you-down/
These times (or powers) may seem small when looked at over small distances, but when accumulated over large distances add up to some pretty significant times (or extra energy required).

Simple: dynohub for (1) lighting (2) a USB charging device.
During the day when lights don’t need power, the latter charges my GPS, phone, tail lights, and if needed my 5000mA hour battery bank (my backup power source if the hub ever quits, which it hasn’t in 5 years due to meticulous wiring and wire waterproofing).
And a wall outlet charger just in case.
Have gone 1400k needing nothing but the dynohub to keep it all running.

The Cascade 1400 thoughtfully provided a variety of chargers at a designated charging area at each control. Seeing the mess of cables and devices underlined how electronics have infiltrated a originally fully human powered sport. One rider had a device that could not be removed from his bike so we ran an extension cord outside to his bike. (Maybe for the frame's structural integrity field generator? That bike seemed not to be of this century.) Watching riders remove devices from bikes, find personal chargers and cables in luggage, plug devices into chargers, then retrieve them, reinstall on bikes, pack away personal chargers and cables made me realize this is an entirely new time sink at overnight controls.
My advice is minimize the stuff that needs charging. Keep your phone off or in airplane mode and carry a small power bank to power it in an emergency. Power your lights and gps off a generator hub. Use a flashing tail light that takes replaceable batteries.

John,
Next year a full series required.
In the past, the longest brevet you finish in the year previous to PBP determines when you can sign up for PBP. Folks more expert than me can tell you if this is still the case. This came to being because registration was climbing and ACP probably wanted a way of limiting numbers and increase successful finishing.
I have been told that no one didn't get in with, for example, a 400 only etc.
Personally, I would not recommend entering without two series under my belt.

OK this is still not quite clear for a first timer. I understand that if I complete an ACP series 200-600K this year I will have a good shot at early qualification next year. But do I also have to complete the series next year before PBP? I realize it's a good idea to build up endurance and to test other things (food, equipment), but is it a requirement to ride the series next year as well? Thanks, John

Hi Dija,
To amplify on what Jake said, that's correct that they just need to be ACP (or RM) sanctioned.
The policy for 2022 is that your *longest* ACP or RM ride is what counts in giving you a chance to register earlier in 2023 for PBP, and thus get more choice of starting waves. You don't have to do a full series, but may wish to for training and experience. Actual qualification to ride PBP is completing an SR series in 2023, of course.
Good luck with the parenting!

For PBP all that matters is the qualifiers are ACP sanctioned and you have ACP certificate numbers to prove it. They don't all need to be in the same country.
Remember for PBP you need to have certificate numbers by the end of June. It can be a difficult timeline for people in parts of the country where it's still pretty cold until May. I'm envious of the people in California and Texas that are qualified by March. :)

No free lunch: ever waste time looking for a place to charge, and fiddling with all that, gear? Burn up your power output carrying batteries up every hill and mountain? Stop just to buy disposable batteries? Slow your roll in the dark because your battery lights don't cast a good beam? All that time adds up. Having done this both ways, when self-supporting I think dyno v. battery is a wash in terms of time, and I'll take the simplicity of the dyno system. G
