Hi again, Iain
I am now on my Mac and can open up the file.
It's a .gbd file (Gamin database) which opened straight up in Basecamp, running the latest maps Europe NTU 2018.3 It looks near enough OK but:
1. I'll recalculate it, which should bring it up to date
2. I'll zoom in on it and correct any little glitches that I spot, so as to (hopefully) avoid send you up a goat track. I have spotted one at Colfosco... and where the magenta road doesn't follow the newer map's roads at all, sometimes sitting just a little way off them, running very close but parallel. This might not matter too much as they would probably snap into place when run on a modern Garmin GPS device but just in base... It doesn't take long to check a 227 mile route so I'll do it anyway. The reason I think for the slight discrepancy is that, besides now using Basecamp over Mapsource is that the shaping points (they appear as little but flags on my Mac) were on the old maps. The new maps are slightly different. The blue flag doesn't move so BaseCamp draws the route out as closely as it can between them, following an invisible line of breadcrumbs. Whatever the reason, i'll scrub it up as basest I can.
I will change all the points along the route into unannounced shaping points only. You might want to add some more, depending on what software you use, particularly if doing outside of Garmin.
One tip: I always try to re-check my routes, a big scree Mac makes this easier. I particularly check old routes that I bring back to life and ALWAYS any I receive from a third party or convert from tracks. 10 or so minutes spent at home might translate to hours up a mountain in the rain.
One last tip. The route does cross a pass twice, so you might want to check it anyway. I had to do it this at the time as I needed to get back to Arabba.
3. I'll see if I can save it as a .gpx file, which might make your life easier
Stay with, as they say.

PS I remember now how I made the route originally. The map / instructions in the book were not always crystal clear but the town were all neatly listed. I therefore asked Basecamp to rind them all and create a logical route between them all. This it did and it worked well enough for me an a friend to ride it all in a day. It did though mean that sometimes the route deviated off a bit to hit the town centre. I'll tidy tis up if I spot it happening. That being said, it's easy to ignore the instructions, which is what we probably did. It's funny looking at it again after nearly nine years as I can remember a very sharp turn right to enter one of the passes. i found it on the route.
The great thing about the route is that you realise how different some of the passes are from one another. All good, even so,
