Taken up running and want the world and your cousin's wife to know about it? There's an app for that. In fact, there are hundreds.
Ireland is in the middle of an exercise boom with 47 per cent of adults now laying claim to regular physical activity. And running, whether it's jogging, fun-runs, charity half-marathons or punishing triathlons, is well out in front.
Almost one in 10 Irish adults are now running regularly (up to 9pc from 6pc in 2007), according to the latest sports participation survey carried out for the Irish Sports Council.
And in this age of social media and connectivity, if someone you know is pounding the pavement, you are going to hear all about it. Whether you are interested or not.
This year's Dublin Marathon was notable for a record 14,500 entry and the first double-Irish victors in 20 years in Sean Hehir and Maria McCambridge. It also brought us an avalanche of information on Facebook, Twitter, Instagram and across all social media.
The info ranged from the very precise; "Passing Kilmainham at 1hr 55min! 19k! On course for my best time ever!" to the more general, with Canadian celebrity astronaut Chris Hadfield tweeting a pic of a man who ran the course dressed as him (with space-suit) to his million followers.
The various apps for automatic time-keeping and social media connectivity meant that your timeline and Facebook page was probably swamped with inspirational, breathless, "It's great to be alive!" style live-updates.
For those of us sleeping late on a Bank Holiday Monday or heading out for a big, weekend-ending fry-up, the constant stream of "Woo-hoo! I'm running the Dublin Marathon!" updates did get a bit grating. But it is a trend that is here to stay. And even committed sportsmen like Mark Pollock, the blind athlete who is now battling his way back to walking again after paralysis caused by a serious spinal injury, can see the funny side of it. Mark is the inspiration behind Run In The Dark – the continent-spanning, charity fundraising event that will see thousands of runners take to the streets in Dublin, Cork, Belfast, Manchester and as far afield as Rio and Sydney, on November 13.
And he is well aware of the social media side of getting fit.
"It's fantastic that so many people are getting into running and keeping themselves fit now. And I think with the social media side, people are looking for a bit of a pat on the back from their mates, a 'Good on ya! Keep it up!' sort of boost.
"Running can be a bit tough and a bit lonely, especially if you are taking it up and you haven't exercised in years, so people want to feel that they are part of a bigger community, they want to turn it into a social thing.
"And with events like Run In The Dark, you get groups of friends coming together to train and take part. This year, we have heard of pop-up events taking place in cities all over the world, and it's mostly organised through social media".
Mark's advice for runners who want to use apps and social media is: "Don't make it all about stats – use it to tell a story."
"It shouldn't be just about the number of Ks you run or times and stats," he said.
Running is certainly the boom sport of the moment and Sinead Galvin of Athletics Ireland believes there is a connection to our recent economic problems.
"We have seen it over the past four or five years; huge numbers of people are getting into running, partly because you don't really need a lot of kit, just a good pair of runners. You don't need to spend hundreds on gym fees," she says.
