I'm with the JFDI camp. I just popped over from RW forum for a look, lurked a few weeks, posted an introduction, changed my forum name and signed up for Outlaw, all within a couple of weeks.
Since committing myself about October last year(yes that can be read two ways), I have bought my first ever bike, relearned to swim, trained and ran my first proper marathon, got the pirate kit and am now looking forward to my first couple of century rides.
You can do it, but first you need to believe in yourself, and in the advice and support on here.
I am not normally into groups or clubs, in fact I've always shied away from anything that might sound clique or too chummy. But really, without the can do attitude, and esprit de corps of this bunch I wouldn't have bothered my arse.
I firmly believe that if anyone wants to be a pirate then they need to try and do things the pirate way. For me it's what sets them apart from all the rest, and the reason I'm happy to wear the yellow and black other than the red and black of my local tri club.
Set yourself a difficult target and you will rise to it.
