Home Made Training Plans
Training plans come in all shapes and sizes, they need to be tailor made for each individual and represent the race you are training for, there is always common ground in all plans and more detail will be talked about in setting up a plan. I have always set my plans on Excel, it is quite basic but gives you a up to date view of where you are and what you need to do. The view opposite is the main data entry, from here you will enter your weekly mileage and the graphs will be automatically generate as in the views below. The plan is made up of endurance/strength/sharpening and taper all in the correct order and amounts
The longest runs graph as detailed opposite gives you the plan and actual, as you can see from the graph there are lots of gradual increases of distance but also plenty of plateaus and decreases, this is give you every chance of recovery especially after you longest runs that should be more frequent towards the end of the plan.
Weekly mileage is a gradual process that is built on over a long period of time, it is always a good idea to have a good base to work from before starting a plan, time plays tricks with you and without a solid base you could be under increasing pressure to cram too much in in a short space of time, results in maybe injury.
