I do a bit of running and usually like to follow a set training plan for a particular event, e.g 8 week plan for 10k. This helps vary my running and provides a lot of motivation for me. These plans are very easy to find online.
Are there equivalent ones for mtb, e.g. 10 week plan for 24 hour.

There are some training plans on the Merida Mountain Marathon web site (can’t do links)
