Running warm up/down 6:00 
Hydration works! Legs felt much springier than expected. Any uphill tough.
Running 50:20 
If I keep errors small, there is hope! Even with at least 4 errors totaling 6 minuets, I nabbed a bronze! I recognized and recovered efficiently from every bobble! (This is one of the first times I've had a sense of "how did I just get here?")
Competitors: Only Walter had smooth (and bloody) run. Bortz edged me due to my late bobbles; Bob Lux MP again (no idea why); Boltz, Clatterbuck, and Nolan struggled. Many M50's and M55's in low 40's -and 3 F50's under 50 - but they're so young!
S-1: Short first leg (similar to ones I set at Cuivre River Middle) got me. Bearing, saw Tom Nolan meadering, pace count ran out, wnet bit further, curled back. FINALLY I read the terrain on map - found clearing. I just never read the control circle properly - weird. "Aim right to reentrant, turn left" was obvious and fast. Nolan still wandering as I left. -3 minutes
1-7: Very clean, not fast but with hills and vegetation few on Green had any pace - good! Expansive bare rock (ala S Bar F Scout Ranch) was very useful - no veg and well-mapped (except 'grey on green' was hrad to see). From 2 on, I realized that bare rock was best feature and used it well - good adaptation.
7-8: found boulder on hill as AP. Drifted left to first bare rock; hesitation; found subtle spur, ran it. Worked as Clatterbuck joined me - he'd just made huge error. I'm surprised I lost -1.5 minutes here - felt like less.
8-14: Clean to spectator control. Small loop left, "Be Careful". Tight square of controls in rocky, hilly terrain was tough!
14-15: Drifted right onto large rock face. Corrected well. 30s
15-16: Bearing and pace. On wrong side of big reentrant! Why? Oops, compass was set on 14-16 bearing. Bottom of reentrant, read rocks well, up side. Pleased to limit error to 1 minute.
17-18: Ran hard to chute & chute, 30 degrees off, hit chute 60m right of GO control. It was so tempting to "Just wave" at GO control. Ran left, back right - nothing left in legs.
I could have been cleaner, but keeping errors small and 3rd place feel great!
It is clear that the two weeks of hiking, back-packing, and orienteering have been a big physical boost - made possible by the 3 months of increased exercise base. Phase one of retirement is a success!
