Two-time Commonwealth silver medallist Emma Pooley is eager to make a return to the road and go for Olympic gold in 2016.
The 33-year-old claimed road race and time trial silver for Team England in Glasgow last year before deciding to retire from cycling.
That decision came after an impressive career that also saw her claim time trial silver at the 2008 Olympic Games in Beijing and World Championship gold in 2010 and bronze in 2011.
Since then she has been focussing on the triathlon but has been tempted back on the bike by the prospect of claiming time trial gold in Brazil next summer and helping Lizzie Armitstead bid for the same colour in the road race.
"This is a truly rare opportunity that I can't resist," she said. "I've decided it's worth a serious attempt at targeting that event.
"If I can prove to both myself and the GB team selectors that I have the capacity to win the time trial in Rio, I'll compete for selection for the Olympic team - I'm happy knowing I won't get selected unless I really do have the potential to win.
"I have no desire to go to the Rio Games, and sacrifice some of the most exciting triathlon races of the season, just for the experience of another Olympics - I'm committed to aiming for gold."
