awesome man... I keep seeing these pop up and makes me want to get to the point that I can do one... I was sitting in the long distance forum the other day and for some reason read though the a century a month thread... I've got my goal for 2014... should be a fun year haha...
as for the HRM dieing... mine did that about a few weeks ago... I didn't replace it for a while... now that I have I am not looking at it near as much even... just going with the "feel it" method... although on a century I'd prob want something to tell me "slow down stupid"
