I've just been looking at my training totals so far for this year.
In 2006 I have covered:
Swim: 50,536yds = 28.7 miles (45.9km)
Bike: 1689.7 miles (2705km)
Run: 510.1 miles (820.9km)
This is the equivalent of 11.9 Ironman triathlons (geez, within a tenth of a mile of finishing my 12th) plus 3 century rides plus 7.5 free-standing marathons, and another 47.9 bike miles.
And I'm not even approaching the mileage some of the rest of you have been putting in.
We are awesome, gang.
