Hi Janet,
Leaving asides concerns over how you like your beer and your carp..............................
Suggestions:
1. Get divorced
2. If you want to do that grand tour de force it will take (according to my canal planner programme) 180 hours - that.s using Trent and Mersey, Coventry, North Oxford, Grand Union, Thames, South Oxford, North Oxford, Coverntry and Trent & Mersey again. You xcould avoid repeating canals by going back via Birmingham and round the Shroppie, Middlewich and then back down T & M to Stone. But even going direct it is 9 hours a day - every day. What are you, some sort of masochist? For me 4 hours is a long day.
3. Alternatively, Caldon canal and Maccalsfield and Upper Peak Forest are worth doing - particularly visiting Bugsworth on Upper Peak. Much less time cruising = more time for BBQs, pub visits etc.
4. If you haven't already found it http://www2.mihalis.net/canal/cgi-bin/canal.cgi is a good site for planning purposes.
