10 Miles 1:15:21 7:32 average per mile 1:30 pm)upper 60's Sunny & Breezy Second time running this road and wanted to make it to the second tunnel this time. The second tunnel is just before the 5 mile mark. Unlike the first tunnel this tunnel is open and you can go through it. Pictures above. First 5 miles is slightly up hill 7500 ft to 8400 ft. My miles were in the 8:30's range. Coming back it's slightly downhill and I was running 6:30's and pushed hard last mile for a 6:06 mile.
