"To help you select the right class and give you a race experience that will provide a life time memory, we have prepared a few recommendations.
All internal combustion engine
(ICE) race classes generally cover between 70-150 kilometres, electric eMoto between 35-60 Kilometres of terrain per day and include a normal mandatory break of 20-30 minutes for
ICE engines at the service point, eMoto's will stay longer for battery charging/ changing batteries.
The estimated riding time is similar for all classes and averages at around 4-10 hours."
Not sure how this would work is it a clover leaf type event so you return to a central refuelling/ recharging point or do you need your team meeting up with you at different locations? If clover leaf Maybe Stark future would step in with a big quiet 3 phase generator to fast charge (or faster than the 2 hours with 240v) all of the starks competing in this event, I do think for this kind of thing to take off this is what is required or are the organisers going to provide a power supply.
Another option would be to run 2 bikes riding one whilst the other is on charge, sounds mad but they did it in formula E up until a few years ago, that way you could maybe do the same distances as the ICE bikes as long as the recharging points worked in.
I was supposed to do the romaniacs a few years ago I was entered but had to pull out which is why they send me these E mails each year, From memory there is a quite long Liason from the town and back each day not sure how this will work in. Lots of questions but E motos need events to work around there range but no doubt the organisers are aware of that.
