Did a trail run to coliseum for the first time. The first 7km were easy and then I reached the turn off. At this point, the trail got steeper, similar to BCMC. The trail was marked with tape but I felt I had to pay attention and look for the yellow tree markers or orange tape. The trail goes up and down and got muddy at times. There was 1 easy scramble. Made it to the top of coliseum 2 hrs after the turnoff. There was a view and I was above the clouds. The way down wasn’t much faster than up. The flat 7km back to the car felt long. Took me around 6 hrs return, running the flats and the down.
