I ran at the field house today since it was rainy outside, which I haven't done in a few months. The track is absolutely flat and was easy to run on. Technically I ran 6 miles (45 laps where 7.5 laps = one mile), but I really think it was more. The sign at the track states that one lap = 211 m, but I was timing myself and I ran the first mile in 10:22. I know I was running faster than that, so I reasoned that the outside lane (which I ran the first mile in) must be farther than 211 m. Using the formula for the circumference of a circle (are you proud Mom?) I calculated that the outside lane is closer to 230 m in length if I estimate that the radius is 3 m larger than the inside loop (I stepped it off) and that the 211 m refers to the inside loop. Anyway I ran somewhere between 6 and 6.3 miles, which is a new personal best! I could feel tenderness in my knees towards the end, but they weren't painful. I finished in 63:30. |
