Biking today. 
Tbh, I work pretty hard to avoid taking groups biking. Used to do some health cycle stuff and the odd Bikeability but draw the line there. 
Filled a gap on a funded ride leader course today to keep that minimal bit of work riding minimally up to date qualified.
Not the most inspiring course but I suspect that's more me being way ahead of the target audience than the course content. Nice to surprise catch up with J though.
