I’ve used a single-page chart to track my weekly mileage for each marathon I’ve run. I like that I can see at a glance if I’m running enough, doing enough strength training, completely neglecting the yoga I planned to do regularly, or see when I’ve been sick, injured, or out of town. Since I’m a total pack rat and keep all the old ones, they also serve as a good reference for comparing my current training cycle to training for past marathons.
I typically pencil-in future races or key workouts to build a rough training and racing schedule for myself and then fill in the actual daily info in pen as I go. At the end of each week, I tally up the kilometres and write them on the line at the end of each row. This sample chart is from my 2009 BMO Vancouver Marathon and is typical of the scribbled mess I end up with by race day.
Since I can’t be bothered to figure out how to hide this behind a password-protected wall, here is a link to the PDF of the training chart for Victoria, Okanagan, and Portland I told everyone about at the first night of the clinic.
In case you want to go back in time, here is the training chart for the 2010 BMO Vancouver Marathon.
