Ultracycling

I mean, I think so. They've not got my money so I dunno if I'm in or not.

Assuming I'm in, I'll probably fly to Frankfurt (another reminder that Brexit was fucking dumb) and train down to wherever the start is via Mannheim or Heidelberg

First of all, thank you for your registration. We are super exited about over 160 registrations in just under four hours, which we definitely did not expect.
What happens next?
We will begin by reviewing the flood of registrations. As mentioned before, we have a limit of 100 participants...
Unfortunately, this means that there will already be a well-filled waiting list. This means that only two-thirds of those registered will have a guaranteed spot, while the rest will need to be patient. Based on our experience, there will be a certain amount of cancellations, so there is hope for those on the waiting list to still have a chance.
The email confirming the starting spots will be sent to you in the next few days.

Could just ride the route any time I want. Just like the social aspect of a bunch of stressed/tired bike nerds on one route :)
