麥理浩徑 6+7+8

全程不少於 20 km in 7 hr，用水 3 升 。是日頭段意志消沈。

The toughest challenge of course is the uphill part to Needle Hill (up 400+m in 1.5 km).  It has 2 parts & took almost an hour to finish it (as exhausted as Stage 4 initial uphill).  The rest uphills are just concrete upslope of which one can adjust the speed.  The initial uphill in Stage 8 takes about 30 min, then plateau, then concrete road uphill to the white doom.  One could consider the bushes between M130-131 & the pavilion between M143-144 as rest points.  No water refill after Stage 7 until the snack store at the end of Stage 8.
