Hike #5! The famous Flatiron and the hardest hike in the challenge. I used to hike this a lot in the past and was sort of not looking forward to repeating this hike again. The trail starts very easy going into the canyon but then proceeds to go straight up. Lotsa scrambling included and some almost rock climbing sections. Nothing too hard or dangerous tho! We have spent about 5 and 1/2 hours on this hike and had great time. This hike definitely felt easier to me now than other times when I hiked this trail in the past. The weather was on our side, partly cloudy, cooler and lotsa shady spots on the trail. Saw few other challengers too!
