Tourist Route the Plan

I have a plan.

So i'm going along the lines of using stairs. My original idea was to have a set route in which tourists can walk and burn off calories walking up all the stairs of Edinburgh and end in the local pub where depending on how many calories they burned off they got to eat... for free. 

However after talking it over with a lecturer and a friend i have managed to come up with a new idea. keeping with the free food/drink at the end because it was a big factor on peoples opinions. I will now create an app that will let you race with friends to burn the most calories, i am not sure if i will have a time limit yet, but in the end the winner gets a pint on the house.
