Organise a Regular Five-a-Side Football Game

Booking the pitch is easy. Getting ten people to turn up on the same Tuesday is where it dies. This builds a system for a reliable weekly game: finding and booking a venue, splitting the cost, sizing the player pool so you always field a full game, and a confirmation routine that stops last-minute dropouts wrecking it. For whoever ends up organising.

You want to play regular five-a-side football with a group of friends but it always seems to collapse due to logistics and people dropping out at the last minute.

Create a system for running a reliable weekly five-a-side game:
1. Finding a venue: pitches, booking systems, and cost splitting
2. Building a pool of players: how many to have on the list to guarantee a full game
3. Confirming attendance: the best way to manage drop-outs without drama
4. Handling mixed ability in a friendly way
5. Keeping it going long-term: the two things that kill regular games
