Having just done an ultra and having kind of made up my training plan I thought I would look at what advice is out there for training to achieve the ultra distance.
This article is a nice one. Seems an honest article covering a broad range of topics but also in an unbiased fashion. There is no black and white rule about the right method of training for an ultra and this article embraces that fact and gives a number of approaches, strategies and ideas.
Very much worth a read if you are thinking about running an ultra!
