I found when doing Ben Alder with the aid of a bike that although the cycle in was tiring I was quickly ready for the walk and felt very fresh once I started. Similarly after the walk I was tired and my feet were tired, however I was then fresh for the cycle back. Different muscles, my feet getting a break, whatever it was I found that I was very glad to have chosen to bike in.
I had previously done it on foot, but that was over several days, camping at Culra.
I had a similar experience when I did the Glen Feshie munros which involved cycling to the car park near Auchlean from Aviemore. My legs were pretty hammered on the last three miles along glen Feshie, but when I started cycling back to Aviemore it was not nearly as bad as expected. Walking and cycling hit different leg muscles hardest, and it helps that the bike supports your body weight when cycling.
