I set my Strava app going on the 1st tee at Church Stretton. With 740 feet of climbing involved, it is currently the hilliest golf walk I've done in the UK. By comparison, Welshpool is 546 feet, Cleeve 540, JCB 503, Kington 471 and Painswick 425.
Not done Strathpeffer Spa yet, which I've heard is a proper lung buster. Haven't measured my old Pennine haunts either.
