We were in Felsted in Essex, and only got a wrist band and a reflective band each.
We chose a spot just after the sharp 90-degree bend, because the riders would have slowed down. There was a decent crowd, two deep in most places, but not massive - it was after all a working day and just one village.
After the race had passed through, however, we walked round the corner to the (smallish) spectator park. The whole village north of the bend was packed and we hadn't realised.
Good day out.
