I've done some further work on the BGR schedule calculator - http://bobwightman.co.uk/run/bgr_sch...calculator.php - you can now mix and match schedules. So, for example, you could aim for a 20hr schedule as far as Dunmail, then drop back to a 22hr schedule to Honister and a 23hr schedule to the finish. You don't have to specify all three schedules as the code will complete when it comes across the entry for Keswick Moot Hall. You can also make an adjustment to your time for the rocky sections (Halls Fell, Bowfell to Scafell and Great Gable) if you struggle on this sort of terrain.
If you've used the calculator recently, you'll need to reset your schedule as the underlying cookie has changed dramatically so it won't work with this version. It's just a case of re-entering your details.
This update also fixes a bug that appeared recently in the schedule estimator page that only affected users of Internet Explorer.
