Note
After a bit of rest, and because orienteering has been relatively nice to my feet (and because it was one last day in Switzerland I could do some technical orienteering) I decided to run a course.
Overall I am quite pleased with my result.
Technically, I'd aggresively estimate I lost 3 minutes of time across the course, largely just hesitation. It was great to get out and see what the kids have been running on - this was quite a challenging area - though not my favorite for a regular course. Contours & fields and route-choices (mostly just side-hill optimization) were much like BAOC. Forests were a bit different, but not much different than a mix of a few thicker US forests. There were some crazy large rocks strewn around here and there, but then many areas of few rocks and intricate contours.
Physically, I prepared largely as I did for O-ringen with a lot of tape and a gradual walk & jogs warm up. One taping difference: on the R-foot, did and arch curl/crunch while placing the diagonals of tape under the arch. This felt a little tighter than past tapings, especially as I initially stood up I thought I might have to remove ~3 minute worth of tape... But it loosened just enough that it didn't bit to hard into the skin. AND, this was the best my foot had felt all day - at least on the initial walk, and even partway through the warmup, the R-foot was blessedly pain free. During the race, the feet did gradually get sore, and I did have to take it quite careful on the downhills (largely landing on toes), but I felt I could push uphill full (current) speed, and it was thick enough, that even if my top foot-okay speed was 7-8min/km, that was rarely a limiting factor.
Feet did feel a bit sore after I finished - did some sandals in the field as a way to try and recover a bit.
