I think its claimed at 6.5. It runs fast and a direct line. My non skiing girl like it when i go to Wildcat because she knows I'll be home in time to prep and cook dinner lolI've timed it in the past. When they run it at full speed, which they usually do, it takes next to no time to get up the 6,610 feet of incline, 2,000 feet vertical rise, from base to summit. I can't remember the number of minutes. Could it be 4 minutes?? or 7 ??
