Hi, we are preparing for hiking to the summit on July 6th. Does anyone know how many miles and elevation gain the chute is? We did a training hike that was 2.8 miles and had 2,700 ft of elevation gain, in the snow, and only used hiking boots and hiking poles. We are trying to get an idea of how that would compare to the chute on Mt Whitney - any insights would be very helpful. Thank you !
