That’s nowhere near Black Sail, although Black Sail might be preferable. That’s one hell of a route OP has chosen. If you are serious about going that way, I’d get your walking boots out, and leave the bikes behind. Haycock is a big, big mountain, and you won’t breeze up or down it.
What are you going to do once you’re at Ennerdale? You are a long way from anywhere just there. Don’t say you’ll ride it back, because that WILL be over Black Sail.
Going in the next couple of weeks? Do you know what mountain top conditions are like at close on 3000′? Ice axes and crampons are a must, along with the ability to use them. If you persist in going then key this number into your mobile – 999. You’ll need it.
Sorry to be a Jonah, but that is a big mountain route in summer. In the middle of the hardest winter for 20 years it borders on lunacy.
