Accommodation Info and Links
Aviemore and the Rothiemurcus/Glenmore are are very well set up for an overnight stay, and longer visits as part of yourt trip to Aviemore Triathlon. There are loads of outdoor activities locally, massive forests, great mountains, lots of visitor attractions (including the Reindeer Centre and the Cairngorm Funicular - both almost on the race course!).
There are good accomodation options at race HQ itself (links below), and the town of Aviemore (which has plenty of Hotel, B+B and Hostel options) is a few minutes from the start line.
