Three weeks ago, the furthest I (thought I) could run was 2 miles.
Two weeks ago, the furthest I could run was 4 miles. And in the three times I ran 4 miles since, I went from 48 minutes, to 44, to now under 40!
Last week, I conquered 6 (and a half) miles in freezing weather.
This week, I will aim for 8. And probably take it easier next week.
Theoretically, this is a linear relationship. Therefore, in 10 weeks I should be able to run 20 miles, and in 100 weeks I should be able to run 200 miles. Yeah, right!
