I'm currently in training for a long distance charity walk (100km) however I've started to notice a reoccuring issue that has come about on my longer walks (30km+) that oddly I don't tend to get when cycling long distances and that is in the days after a longer walk my lips get really dry and chapped. At first I thought it might be a hydration issue but I've really dialled that in and on my most recent hike where I covered 75km in 12 1/2 hours I was able to keep really well hydrated with of places to refill my hydration bladder and made sure I was regularly topping up with electrolytes. I also made sure to keep applying the vaseline I was carrying for other chafing related issues regularly but still in the days following my lips are really painful.
The only thing I can think of is that I tend to do these longer distances on fairer days and it could be something to do with sun exposure but I'm not sure because I didn't burn anywhere else? I must admit that I've really only been walking properly like this for the last year or 2 and the last time I was doing distances like these was when I was a teenager so I still have a fair amount to learn and hopefully someone might have a few tips or tricks to pass on.
I get chapped lips all the time. I guess just wind etc will do it. I use Carmex lip balm, it's amazingly effective. Or on sunny days, I have a Nivea one with a high SPF while I am out and use the Carmex when I get back.
I use snowfire for my lips. Never go anywhere without a tube. Been using it since I was a child. Easily the best thing out there imo. Takes away the pain/annoyance of chapped lips.
Take it skiing, hiking, mtbiking and even surfing.
Smear your lips with sheep droppings.....it disnae cure chapped lips, but it sure as hell stops you licking them.
I was talking about this to an old farmer many years ago. He said to rub some cow manure on them. 'Will it help?' I asked. 'No' he replied ' but it'll stop you licking your lips'.
