I dispute the claim that the walkers who walk ahead and faster leaving the others behind are the more experienced walkers.
All it shows is that they are any or all of these:
1. inexperienced leaders
2. use walks as speed challenges or exercise
3. self -centred
5. see the destination as a goal and not the enjoyment of the walk
6. have yet to learn how to observe what goes on around them
7. think "distance or speed matters" not quality
8. have not learnt to pace themselves
9 are probably not woodsmen / woodswomen just "hikers"
10 call walks "hikes" or "treks"
11 often are restless during overnight camping
My preference when taking a group out is to be the tail end Charlie and let the trail pounders go ahead with a colleague to lead, if necessary. The noise made by the group will scare game off anyway and I have time to stop and look which is difficult if people are walking behind you.
If needed, I close up with the stragglers who often, wahtever the reason for being slow, are more open to the enjoyment of the walk and interesting people. The braggers are often at the front of the group.
