I got pilot test and than bought a £90 bundle for my Scotland trip , I did 450km cycling north from Corrour around Caringorms south to Perth and back to Corrour through Kilin ad Rannoch Moor . I would highly recommend Styrk fuel planner . Perhaps for me it was too much but after 4 days of 10h ride a day I got through almost all of it . Bars are especially great treats. One thing to remember is what the planner says , you need other food too. Personally I found greasy staples as pork and beef pies an ideal combo
