Gonna have to buy another bike ain’t I.So that's a 72.5" gear - fairly low. I wouldn't have thought you would have any problem getting up Hartside but maybe fkn difficult in other places. Actually that gear would be more of a pain in the arse to ride downhill than anything else. I usually have about 87" setup but stay away from big hills. Basically the c2c isn't a ride for fixed gear.
