Search you tube for GCN ( global cycling network) lots of instructional videos including bike set up. I would get bored doing the same route . I would find 3 or more loops .Hard but short .medium ,easier and flatter and rotate them if your not feeling it do the easier and if your up for it do the hard. Climbing is a mental challenge just try and get further up each time . If you stop try not to walk ,rest and go again so you know you can climb the hill. Good luck and keep enjoying that matters the most
