OK here goes - I found my old profile (currently in relationship so not using it now)
This is a 'standard' profile on match.com - the first bit is the bio you write yourself and is pretty short, then the sections that follow are bits you fill in about yourself so they are a bit like 'prompts'.
I suppose you could use this as a bit of a guide but maybe too much info for a general 'chatty' intro rather than match.com, which seems to require inside leg measurement, shoe size etc etc (though you can just decline to answer some of the questions without any problems). I've not posted the whole lot as it's too long but this should give you an idea 
Why don't you post something here and maybe we can give suggestions! My friends and my boss helped me write mine and post it whilst drinking wine and then spent ages laughing at the people who messaged me. It's great fun...
Small energetic female with bicycles (3) seeks like-minded man!
Hi!
I'm looking for fun, friendship and hopefully finally love from a like-minded man! Whether or not there is someone out there QUITE like me is up for debate. My friends would describe me as a bit of a nutter. Over the past few years, amongst 'normal' physical activities I have done a marathon, an Ironman, a 24hr TT and a 24hr MTB race solo!
I'd like to meet someone to share these activities with. If you like combining the above with good food and wine then so much the better!
Life's pleasures include being outside; smiling horses, dogs and people (yes horses and dogs do smile - please don't argue with me about this); that fuzzy feeling when you're just waking up and it's too nice and warm under the duvet - preferably with someone lovely; and fun with friends.
Life's irritations include rude arrogant people, especially when behind the wheel of a car (and particularly when I am riding my bike); the wrong amount of Nutella on wholemeal toast in the morning; toilet paper the wrong way round - it goes over the top, not underneath; and odd-coloured pegs on items of washing on the line (no I do not have OCD)!
More about me
What do you do for fun?
Most of my spare time is spent doing something active. My friends are all into triathlon, or running / cycling as individual sports. I do like a nice meal out, or trip to the cinema to chill out though!
Favourite local hot spots or travel destinations?
Favourite places: Vancouver, BC where I went to race a triathlon a few years back and then went MTB riding in Whistler. Also the Alps, accompanied by a bike (and hopefully good company)!
Favourite things?
Riding the bike (recognise a theme here?!), being with friends - either catching up over food & wine or out doing something active.
What is your favourite book?
I don't really have a favourite
