Hi Grier -
My through hike on the Coast to Coast was way back in 1985, so not terribly relevant now. That said, I completed some of the Lake District sections last year and was on it on the North Yorkshire Moors (and coast) where it runs in tandem with the Cleveland Way a couple of months back. Like you, I am approaching seventy from the wrong direction!
In terms of preparation I would be getting in lots of regular walks and, if possible, including plenty of hills in them. While the peaks in England are admittedly not high in terms of sheer altitude on the Coast to Coast the ascents and descents are relentless throughout the walk. For that reason alone I would be taking walking poles - they really do take some stress off the knees especially, on both ascents and descents, plus they provide additional balance on the more rocky trails especially in the Lake District for instance.
So what do I wear on an English long distance trail? I should state that I tend to ‘run hot’ so am happy in thin layers. Thus I wear a wicking t-shirt and if I need to be warmer I wear a thin long sleeved half zip base layer on top of the t-shirt. I have added a couple of hooded versions of these to my wardrobe. In summer I try to wear shorts but have longer hiking pants in my main luggage as back up if the weather conditions require it. (This I ascertain by reading the weather forecast and looking out the window first thing of a morning - this doesn’t always work and thus I found myself in shorts at the highest point of the North Yorkshire Moors on a day when some folk were helicoptered off with hypothermia, although we were ostensibly in the grip of what Brits refer to as a ‘heatwave’! It was a bit brisk around the knees, but if needed - I didn’t feel the need as it happened - I had my full length waterproof trousers in my day bag.)
I always carry full body cover waterproofs in my day bag as a matter of course. In August I would think you would get away with a lighter weight waterproof jacket and waterproof pants. On the Cleveland Way I wore a very light windproof jacket which I also had - your waterproof would double as a windprooof if you wanted to save weight. I had both but never wore the waterproof as the weather was (remarkably) dry. That said, because weather conditions are so changeable and localised here, the waterproofs were in my bag every day without fail. I wear a baseball cap or ‘flat ‘at’ on my head if conditions allow but have a lightweight beanie for when the wind gets up. There’s also a pair of gloves and a Buff (or similar) in the day bag, every day.
I wore lightweight hiking boots on my latest Coast to Coast section hikes. What works for me are a pair of liner socks and a thicker merino pair on top of those. My boots therefore are a size larger than my regular footwear. I arrived at this system by trial and error over a long period - works for me, but I recognise that everybody is different and it may not work for them. I know the tendency these days is to hike in ‘trail shoes’ and if you can get away with that, fine. Mostly, whether to go with boots or shoes depends on a) how wet or dry it is underfoot, b) how rugged your trail shoes are in comparison to boots, and c) whether you feel the additional ankle support offered by even a lighter weight boot is necessary/desireable (on balance I think I do).
I am normally a fan of knee length gaiters but noted my lightweight boots don’t have the indent in front of the heel section to accommodate the underfoot strap, so left them at home. If the weather had been especially wet, I would have switched to a heavier duty boot and taken the gaiters but as it was I was prepared to risk the vagaries of the British summer!
