One big, outsized climb. Gained over 6500' and the climb topped out at 9453'. I was told it goes to 10,024' but I could not find the hookup for the final 600'. It's about 40 miles r/t from the turnoff at Whitney Portal Road. Four bottle ride - there's water at the trailheads up top. The second climb was to have been Whitney Portal but I had to bail. The temp was 105 when I started the Portal climb. My HR was at 90% max on the jump ups before the switchbacks so I turned back. High humidity is tough for me. Beautiful climb. Have never seen a bigger, steeper, higher reaching ride. The Jumbotron.
