FM, with all of the running that you have been doing through the winter, you are in a really good position for the start of your training. I have a feeling that you're going to do great!
On a different note, my wife got me an early Valentine's day present, the Garmin 620 watch that I've been wanting for a while. I took it for a quick 1/4th mile run on the treadmill last night just to play with the data points that it provides for running analytics. I think this watch is going to be quite a good bit of fun for me to over-analyze the data
Plenty of reports that the GPS functionality on it is a little less consistent than my 210 that I have been using, but I'm thinking with all of the new features, that won't be a huge deal with how I usually run (No real curvy paths or runs through cities with tall buildings) so I think it will be fine.
Also on yet another unrelated note.. Anyone else watching the NBC coverage of the olympics throughout the day.. I've become addicted to that Reebok commercial for their new running shoe (the one with the underdog theme song). Every time it comes on, I stop what I am doing to watch it. All I know is that I need to go somewhere with a subway train like that commercial so I can do whatever they are doing in that spot. Some kind of 3 team race between subway stops looked really fun in that commercial!
