Squeeze a run into your lunch break at Tower Bridge
If you work in the Square Mile, this is your club. Started in 1997 by London insurance-market folk but open to all, we're the City's go-to for a midday or after-work run.
We meet daily at 1:10pm at the north-east end of Tower Bridge - speed sessions Tuesday and Thursday, steady ~5-mile group runs the other days, and a beginners' group on Thursdays. All abilities, a friendly jumble of paces, and dead convenient if your day's chained to a desk.
Honestly the easiest way to fit running into a working day in the City. Come down at 1:10.
