I attempted to do it in 2003. Along with my mate who's an ex-Para and his son who had just come out of the army stationed at Hereford and was "quite fit"

, we worked out a schedule and decided to do the walk in 5 days.
Typical me: I snapped a D Ring on my walking boots on when I was putting them on to start the epic journey. This resulted in my foot moving around inside the boot causing a bit of friction. I was forced to wear appraoch trainer shoes. Not ideal.
Day 1: Milngarvie to Drymen. No problem.
Day 2: Drymen to Inversnaid. Apart from the distance (IIRC it was well over twenty five miles) this also entailed walking over Ben Lomond. We walked for about 15 hours that day and my feet were covered in blisters. I really knew that I was finished but my mates and my stubborn steak told me otherwise.
Day 3: Inversnaid to Invernam. By the time I got to here, I was wringing blood out of my socks and SAS bandaged feet. I was in agony and decided that my stubborness and determination not to give in was bordering on insanity. I can remember the relief when I decided to call it a day.
My 2 mates were a bit miffed and I think they took it a bit too seriously, like an army excerise when in fact, it was supposed to be fun.
I made my way over to the hotel at Ardlui where I waited about 3 hours on my wife picking me up. I've never been so glad to see her.
My mates did it in the planned time with two further overnighters at Tyndrum and King's House Hotel, Glencoe (which was the most expensive and by far the worst accomodation on the entire trip).
I don't know if I would have been able to keep that pace over that length of time regardless of blistered feet as it was punishing and you saw feck all, with your head down and trecking (or tabbing) at very fast pace.
As G.C. said, the bit that I did wasn't that spectacular scenery wise (what I saw anyway

) and I missed the best part (Crianlarich north). I'll do it again one day (the walk from Inveranam) but not over 2.5 days!
Take your time and enjoy the walk and scenery. It's the only way to go
