I can almost walk again though

Just a small suggestion to vary the format: fix the *finishing* station. People synchronise watches when they meet, and start wherever they like at a fixed time, e.g. 1pm, even if there is no train in the platform at that time. That way, the participants are really racing each other to get to the finishing station, so it will be very visual who has won.
I agree that we shouldn't do this too much though, let's give it till September at least.
