Tempo's in the mountains

I used the climb to Fighting Creek Gap (Laurel Falls Trail Head) starting at the park boundary with Gatlinburg for the first tempo effort. Took me exactly 23 minutes from the park border to the top averaging 295 watts, HR around 145. The next effort started at Sugarlands and went towards the Chimney Top picnic area. Didn't make it that far in 17 minutes but still covered some ground and averaged 290 watts. Just for fun I headed back to Gatlinburg and rode Cherokee Orchard Road and then the Roaring Fork Motorway. That road has some great sections at 17-18%. Ended up with just 3 miles in 2:45 but got in 4500' of climbing.
