In the referenced race, Georgia/GiGi Blair and Alan Lopez (64, 65) also count as orienteers.
In later races Tony and Karen Muffati had very respectable results, and I'm probably forgetting a few.
Steve's win in '81 got my attention,as well as the attention of race director Dick Vincent, who always gave orienteers great respect, and possibly breaks on his entry standards, which he had for safety reasons. He said he didn't need to worry about us.
The following year, you won't see me on the winners list, but I beat Steve's course record by 12+? minutes. Problem was that Bill Glatz (#3 behind Steve in "81) broke it by more. We were pushing each other together near the end, when I hit the the wall (one of my few times ever) and he didn't. Despite successful attempts in "84 and '87, I never got his time.
If you can do the Highlander, you can do this one. It's slightly longer than a road marathon, time-wise, but it doesn't beat you up as much. Orienteers have an advantage on the extra rocky stuff, and downhills. My advice for the uphills is don't bother trying to run the steep stuff, just hike hard at your threshold level. I did much more walking than those around me.
Thanks for posting.
