Just a question about this *Clicky*. It's an 8 week programme that looks to be a piece of piss to complete, but I'm not so sure I'll be able to go swimming twice- or even once- every week. I work irregular hours at work and I never know what days I'm working- it's a pain in the arse. I could have a week off, or I could work 7 days. I can never guarantee anything. Do you guys think it will matter if I mix it up a bit? Replace a swim with a bike ride but do the swim another time or something like that? So get the stuff done in the 8 weeks but in a different order. I know it sounds stupid, but I'm not sure if it'll really make a difference and don't want to cause myself any problems or injuries.
