I thought our second batch hike (actually the first, not counting the one last year as we were broken up into groups) went great. Our batch showed great enthusiasm and willingness to push ourselves beyond our limits and were able to complete 36.5 km on 9 hours (with stops and lunch breaks). We left at 10 am and reached back ant roughly 7 pm.
