Over the last few years I've worked hard on climbing, tough going when it's flat as a pancake for miles round here, about 25/30 miles to any decent hills. I like the challenge of them, there's usually fantastic scenery where there's hills & they are all different
I attempted Swiss Hill earlier this year & failed, it had been damp & drizzly most of the day & when I arrived there the cobbles were quite slippy, so much so that my rear wheel kept spinning & I was just getting slower & slower, until eventually I had to stop on the end of a driveway. I used their tarmac drive to get some momentum again, but it was all in vain
When it goes left & climbs again I had to quit & turn right
So on that basis it gets my vote for least favourite of 2019
