Here are mileage totals from my 2007 training log:
Running: 1,515 miles (220 hours)
Cycling: 585 miles (31 hours)
Swimming: 48 miles (24 hours)
Total: 2,148 miles (275 hours)
275 hours only equates to 3% of the hours in a year. So I have some room to pick up the miles in 2008!
For 2008 I'd like to hit 2,000 running miles for the year. I don't have a specific cycling goal but I'd like to step up the cross training on the bike since cycling is my true passion.
