Any tips for a complete novice?
Is there a Strava group?
Welcome. This is like Hotel California. You can check in any time you like but you can never leave. *evil cackle*

Any tips - don't overdo it. If you've got a good level of basic fitness you'll get to a decent standard / length quite early on and the improvements are quite exponential at the start. Don't be tempted to push it too hard too soon - that way plantar fasciitis lurks. Oh - and do parkrun. If you're down for games then there's a lot of us on here that do it and also a lot of the regular away game boozers do it now too - you'll probably see friendly faces.
