Hello from another Lilac :).
Like you, at 26 I absolutely despaired. Then at 29 met DH and thought, oh that is why nothing else worked out. He really was so much better suited ot me than any man I'd met until then. Married a year later. Together now for over 30 years 
Don't just OLD. Get out into the world doing things you love and are passionate about. While you are single, you have your evenings and weekends free. Use them. Try a variety of things that are good fun and life-enhancing for you whether or not you meet a man, but choose the versions of them where you are more likely to meet a man!
To keep fit, join a gym or bootcamp, a cycling or running club, or go to a climbing wall not a Zumba class.
Do something that contributes socially to an issue you care about - a political party, ecological campaign or charity volunteering.
Go on group adventure holidays to places you really want to see or doing activities you've always wanted to do. Your genuine excitement will be appealing to men who enjoy the same things.
Do things where you are likely to meet like-minded men. DH and I recently signed up for a woodworking course. I am the only woman. I've met perfectly eligible men on creative writing, art and photography courses, meditation weekends - men who are clearly partly there to find a partner as well as to enjoying learning new things.
At very least you'll have an interesting year and loads to talk about on OLDs. And you won't be available all the time, as you'll be busy. Like it or not, men seem to find this very attractive.
