Beautiful route. Hard to avoid the tourists, but otherwise it's a lovely technical trail with a load of climbing, spectacular views, and a nice bitesize adventure. Took one 650ml flask of water + drink mix, which ran out on the final descent, and a flask of PF flow gel. Glad the heatwave has mostly passed, so temps were great. Loved it.
