I run wearing my Garmin watch if at all possible. I upload to the standard connect.garmin.com site.
I view my data on the site and click on "Splits" in the upper right corner.
a video of myself completing the macro. I should look into a way to record what my screen is doing. It is all very quick. Once I run the macro I have the summary columns on the right and the detailed summary below the data.
In my main summary tab, I document the date, time, distance, who I ran with, type of run, description and location. I also have target pace and distance but don't always have those filled out. The file creates mile pace and projected finish at current pace for a bunch of different long races.
I have another tab that has the weekly mileage totals. I also have 2010 and 2011 off to the right of my 2012 data for some quick comparisons.
I have a monthly mileage totals tab too. I also have my Goals for each month too. I have 2011 monthly totals on this sheet as well.
I also have a tab comparing marathon training at different times so I can compare week 10 to week 10 in training to see how that goes. I also have off to the far right my half marathon training in 2010. I ran more for the half than I did for a marathon. I'm the worst at training.
How do you keep track of your running miles? Do you even keep track?
