Trying to raise awareness of Batten Disease as my lovely neighbours have two grandchildren effected by it :( Want to know more about condition? https://en.wikipedia.org/wiki/Batten_disease Briefly about the challenge: Getting to the closest station to the peak (Ben Nevis or Snowden, haven't decided which one yet) by train. From there cycling from peak to peak. Sleeping in B&Bs or other cheap locations to avoid taking a tent - lighter bike, more miles done per day.
