This year`s expanded Hill Challenge series have released their schedule. Sadly, nothing down in Shikoku, the one in Okayama (same as last year) is barely a hill (2.7% - apologies to beginners), the one in Hyogo better but still less than 5% (though second half nearer 7%). The interesting ones are all miles away
