If you’re hoping to get close (REALLY close) to nature and improve your fitness you might just be in luck. The 2nd annual Streak to the Peak nude 4. 6K race has been scheduled in the Boise Mountains on Sept. 8 at Bare Mountain Retreat (30 minutes from Boise on Rocky Canyon Road). Yup. It’s a nude race. "It’s the most challenging nude race in the country," said Jay Johnson, race organizer and member of Bare Mountain Retreat.
