Great Post Mate! I live in the States and am going to look into Park run and read all about it.. Interesting enough I just started to develop a training program for myself with cycling and running yesterday but I now may have to reevaluate it and tweak it out if there are Park runs nearby me - I live about 2 hours from NYC
I've been really surprised how few parkruns there are in the States. If you don't have one nearby you could look into starting one up.
I'm involved in a team that has done just that in the UK and our first run is next month!

I'd like to do more cycling. It's a great way to explore. I don't know how much cycling and running help each other, but general fitness has to be a good thing.
