Starting the year the goal was to get more organised about training, run half marathons for 6-7 months (getting down to sub 1:40) and then train for and run a "well-under-4-hour" marathon in December.
Faster than planned progress on the half times had that goal change from 1:40 to 1:35 and eventually 1:30.
Injury had the marathon goal pushed to 2008.
Mileage for the year was 1,507, with 3 distinct phases:
1) Jan-May. ramping the miles until achilles tendon problems started.
2) Jun-Aug. very little running, deep water running in the pool. misery
3) Sep-Dec. recovery and rebuilding.
I have data and trending for pretty much everything, but the key is really the relationship between speed and heartrate. As you get fitter you can run faster at a given heartrate. If I trend heartrate/speed for my races there is a steady decline. Using that I can project my future performances and see if I am on track to meet them.
Here's the trending for 2007 (bubble size indicates the length of the run, blue line is 3 week trailing average)... Excepting the injury phase, it shows a pretty steady decline from 22ish to 19ish
Overall it was a very successful year for me - I end 2007 way stronger, fitter, faster and smarter (at least about running) than I started it. I went from running 40 miles per week to running over 60, and from 5 days/week to everyday. The achilles injury really changed everything. I realised that it is very easy to push too hard (especially up hills), and that I am not 20 anymore. I've learned a lot about what my body can, and can't put up with - ice has become my friend, stretching is now something that I do everyday. I also learned that it's OK to push thru extreme discomfort when racing, but probably not so smart to do that every day in training.
I'll publish my 2008 goals tomorrow
