Mt Bealey - Avalanche Peak via Lyell Peak traverse is about 12.4 km. It is very exposed most of the time along the ridge line.
The following is the breakdown time to each section for my trip:
Arthur's Pass - Mt Bealey: 2.75 hours
Me Bealey - Lyell Peak: 1 hour
Lyell Peak - Avalanche Peak: 0.75 hours
Avalanche Peak - Arthur's Pass: 1.75 hours
