Let’s be honest: the “Hill” part isn’t a suggestion. You will climb. A lot. I once watched a man in business attire walk his bike up it, and he wasn’t even embarrassed. Nobody is embarrassed.
But here’s the trade-off: the views from the top are stupidly good. On a clear day, you can see the Shard, and the sunsets turn the whole place gold. You earn that view with every puff, and it weirdly makes you feel like a local hero.
