I think you're looking in the right place - the WTRL website. Like Bob said, some of the admins at ZSUN sorted it all out so I don't know the finer details but I would suggest perhaps you make contact via WTRL if anything isn't completely clear from the website rules.Don't really know yet.
Only skim read the website last night, so I don't know if it has to be committed names or a squad. All I saw last night was between 3 and 8 riders. If it was a squad, then as long as we had 3 riders on the night I'm guessing we'd be ok.
They do allocate you to a start pen based on the make up of your team (based on the Cats of the riders) although they do say they'll adjust your finishing place if you start in the wrong pen.
Need to read up on it a bit more. Also to understand how the team name thing works.
Any advice @bridgy @<Tommy> @berty bassett @bobinski ?
I just thought it looked good. Always enjoy watching the team time trials on the pro tour and thought it could be fun to have a go at a virtual one
What I do know is firstly changing your name on Zwiftpower to an exactly correct format was important for picking up team results (i.e our team within ZSUN was Red Giants so I was "Paul Bridgman (ZSUNR - Red Giants)" on ZP and everyone was the same format. Secondly, the starting Pen (or cat A-D) you join is not logical based on the w/kg valuesthat show on ZP or the companion app - your screenshot above shows how its done based on the make up of your team. So for example we had one Cat A in our team and the rest were B's and we had to join the D-Cat or D pen when sigining up for the race. (There is actually some logic to this - it's to keep lone riders who sign up to the event away from the proper teams, so faster teams enter a lower category and slower teams a faster category).
Once you enter a team formally via WTRL they give you a start time, so we had to join the event as normal and for us it was a matter of sitting on the line for 11 minutes before starting - this is the bt you'll need to get sorted with WTRL I guess. Results are then posted on the WTRL website - I think you need to be signed up for an account in the site to get these and I couldn't manage to do that but hopefully you can?
Apart from all that, there's some rules on their website regarding what to do if you catch or get caught by another team etc.
I hope you can manage to get your head round all the admin and get a team entered - it's hard, but good fun!
