## 143Hardrock is only 90 miles!

I just got my Hardrock entry booklet today. Very nicely done, But on page 2
of the course description, item 6, it says:

"All mileage used were obtained by map measurement with on the ground wheel
measurement verifications for over half the course. To correct for vertical
changes on the map measurements, the vertical distances are added directly
to horizontal distances to obtain the totals"

If we subtract the vertical distance (66,000 ft. = 12.5 miles) from the
total distance (101.7 miles), we obtain a horizontal component of 89.2
miles. Then applying Pythagoras' theorem, which is the correct method of
combining horizontal and vertical distances (assuming a constant grade), we
have

sqrt(89.2^2 + 12.5^2) = 90.1 miles.

So this course is really not has hard as everyone says it is :-)

Also, a couple of minor errata:

1. Carl Yates is listed as -27 years old (a lingering Y2K bug maybe, or did
we make an exception to the minimum age requirements?)

2. At the absolute bottom of the all time finishers results (sorted by
time), Fred Vance and I (with * by our names) are listed as finishing
unofficially in 51:08 in '98. Our actual time was 51:38:34 (a blistering
34:23/mile pace, and I had the blisters to prove it).
