I used to visit Darwen regularly when working, I don't mind at all visiting and it would certainly test the bike, its about 25 mile round trip with a 900 ft climb going through Rivington and Belmont, (may need a battery top up when there), I've no idea if the bike - or me can manage that or not - could be fun finding out.
As John stated it is too big for yourself, and may be a touch big for your husband, at 26Kg its certainly on the heavy side, it's raining here now, and the met office says rain tomorrow, but supposed to be fine and dry (though chilly) on Saturday and Sunday, I can send you a message tomorrow if you wish after checking the met office haven't changed their minds.
