I am struggling to find running shorts that fit and don't ride up and that I like.
I've tried a few different pairs of shorts now. I have a pair of Pearl Izumi shorts that I bought cheap in desperation, but they are too high waisted to be comfy. I have a pair of Adidas ones which are ok but ride up a bit. I have a pair of knee-length lycra capris that give me two rubbed spots on my bottom after surprisingly few miles, and a pair of Asics lycra shorts that give me rubbed patches after around 10 miles. The two pairs of Ron Hills I have both have serious issues for me.
I have run most of my races in my Harlot Houlihan shorts, which are actually designed for cycling. They have no seam in the crotch, just a stretchy panel. They do not look like 'proper' running shorts, which I like because otherwise people might assume I'm taking this seriously or that I might be quick or something. They aren't lycra. I don't like going out in skin tight clothes. I'm told it doesn't look too bad, but there's only so many times you can get called 'Camel toe' by a man carrying a brace of poached rabbits before you think better of it. (Turns out my limit is once. I tried not to let it ruin the run, but it wasn't exactly happy-making.)
The only problem with those shorts is that they are quite heavy material, so if we ever get any warm weather they are too hot. Plus I need more than one pair, and they are quite expensive. That's my problem with experimenting with new pairs too. Each new pair is a minimum of £20, often more, and it's not like you can take them for a run then take them back if they don't work.
So, I've been thinking: sewing is becoming another hobby of mine. So can I make my ideal pair of shorts? If I can, I can then make as many as I like. If I can work out what makes the shorts ride up, I should be able to engineer it out (and since not all shorts do it can't just be that my thighs rub and there's no hope).
I've chosen to start from a cheap pair of board shorts. I figure the material ought to be quick drying at the very least. I've started by trying to copy the shape of the Harlot shorts, and put a stretchy panel under the crotch and moved the crotch up a lot. The riding up seems to happen when the shorts move up my leg when I raise it and doesn't move down again after. Having a tighter crotch means the short leg can't move up so much, so shouldn't ruck so much. I'm going to do some further analysis on what makes my other shorts ruck up as well because I think there's something to do with the shape/give around the top. At the moment the stretchy panel is some fleece I had hanging around, but I may buy a metre of something more suitable once I've got something workable.
