This is a great idea, especially to use this as a "bonus" course so that traditionalists don't have to choose one way or the other.
I'm not aware of other orienteering clubs having done this at an event, but there a few orienteering-ish apps out there like Erik linked, which are more geared for non-events (like perma-courses). As far as technology and perma-courses go, I think
where the bears will eat you the Canmore Nordic Centre does something novel.
For 'Hood Hunts (a grassroots urban score-o), we offer 3 ways to play:
1) PYOM (print your own map, from a PDF on the website)
2) Open the PDF on your smart device
3) Download a georeferenced map on your smart device using the Maplets app
While it's not new that people are orienteering using PDF's on devices, it is new that you're providing the map link on the clock.
I'll second Ian's suggestion of also using a QR code. Although, in my experience, it won't get used very often. (Probably because "
QR Codes are Dead")
I represent CascadeOC at the monthly RoadRunner Sports Adventure Runs, and that includes hosting a checkpoint on an orienteering map. There are several ways of getting that map, none of which are on paper:
1) Snap a photo of the map poster we have at our booth at event HQ
2) Visit the map on our Facebook page
3) Scan the QR code at our booth, which directs you to our map online
Very few people use the QR code method. They either don't have a QR code reader, or if they do, they use it so infrequently that they've forgotten how to use it.
I've also been including QR codes on 'Hood Hunt maps. My thought would be that someone who shows up at the event and forgets to bring a paper map can easily get the link from someone who has a paper map. Also, when participants get stopped by curious passersby, they could show them a QR code.
Again, having the QR codes doesn't seem to be a big plus, but they are really easy to set up, so I'll keep doing it until something better comes along.
