The opposite of Haute Route is this one I think. Is that Faible Route?? Or has my French let me down (not spoken for over 20 years)? It looks like it doesn't really go to many fell tops and I'd just walk my own route in the same time it takes to do this one.
In fact I've done something better over 11 days a good few years ago. Called the Lakeland Round. There are two IIRC one is out in a small book (Lambert I think) and is over the ridges but dropping down to villages with accomodation in handy, day sized chunks after sometimes long days. The other is similar but does a slightly different ridge route.This second one is online as many have done it and written it up on their blogs. Worth doing as it is a 12 day trip leaving you a day each end to travel to and from the start.
There is another book I have which has most of the published routes in it. Those routes range from fell races and other multi-day races to backpacking routes like the Cumbrian Way. It is just a basic information on each. Things like a Back o' Skidda' route and the Charnley Way. That is a nice 3 day thing centred on a cairn near Charnley Crag. It was a fell race (one day) that was done in memorial to a guy who helped set up the first KIMM in that area but who died shortly afterwards. It is like three thin loops from that central crag going into three different valleys with YHA and other accommodation. It would make a good three dayer as it goes over most of the interesting hills from Scafell Pike to Borrowdale fells and Langdales.
Anyway, don't mean to belittle the route you have planned. It is still going to be a good route as anywhere in the Lakes is nice. Also at this time of year perhaps valleys are better places to be if the weather comes in hard. Enjoy your trip.
