TriNewbies.com was founded in 1999 to be a main resource for triathlon training and advice. In the following years TriNewbies was a central part of the triathlon community, even hosting a popular forum for triathlon discussion and advice. One of the most popular elements on the website are the triathlon training plans. These plans have been viewed and downloaded tens of thousands of times.
