I ended up in the ghost world again. Ohh well.
I saw a session in warm up, when I started mine at 6 PM. It looked like it could be your avatar picture, when I checked. The possibility of someone else starting that exact route at the same time is slim, so probably was yours. I think I maybe could have joined it, and Randy would still find it, if searching for me. But it would show your picture in the warmup session box, so might confuse him.
Best is to wait for the "racemaster" to start a session and then join that. Do this either by finding it under
Go to my activity ->
Leagues -> Today's route -> Session in warmup, or by searching using racemaster's (nick)name in the normal (🔍) route search box (and select the body symbol). If I am the racemaster search for "brusgaard".
