The Urayasu Runners Club isn't that big, strictly speaking, compared to other running clubs I've been in. It is just that the URC has about 80% attendance at their events - making their active membership enormous, compared to other running clubs I've been in!
In the morning, a group met us at the hotel and walked with us to the park where they hold their club run. It was packed!
We started off with 2 or 3 laps around the park, for about a 1.5 or 2 mile warmup. Then the coach led us through at least 20 minutes of stretching. After that, we ran their training route (about 5K) to another park, where the cooldown workout was a relay event - teams taking turns running back and forth across a field. Then we walked back to the first park, for cooldown stretching and a group massage (so to speak) - everybody lined up in a big circle and we took turns pounding on each other's shoulders. It was pretty fun and felt good!
