Hi
Its my first post too. I've done the Leicester Loop 3 times over the last 30 years, most recently this Easter. We've always done it in a week, so 2 weeks shouldn't be a problem. Things to consider include:
Part of it is on the River Soar, so you need to be careful, especially if there's been heavy rain; it could even be closed if the level is too high. Also be careful of the weirs; they're well guarded, but getting stuck on one can ruin your day. When you first get on the Trent it seems huge, but you're only on it for a short stretch.
Although you'll probably cruise a bit faster on the River, because of the deeper water, the river locks are a lot slower than the canal locks, so factor that into your planning.
The staircases at Foxton and Watford have restricted opening times, and can be very slow to get through when they're busy.
You could consider going up the Erewash too - its quite nice, particularly at the top end. Its good if you like doing locks too ;-).
Around Coventry is a bit bleak, apart from Hawkesbury Junction, so its probably better not to plan to spend a night there. Otherwise its a pretty rural. There's a nice old pub at Sawley.
