The Welshman wishes he could continue to experience the adrenaline rush that coursed through him as he competed in front of 6,000 in the Velodrome.
Colbourne leaves his first Paralympic Games with one gold, a world record and two silver medals to his name.
His silver in the C1-3 time trial on day one of the Games was Britain's first medal, and a day later he clocked 3min 53.881sec to reach the individual pursuit final - a new world record.
After going on to win that final he later claimed his second silver, this time on the road in the time trial at Brands Hatch.
"I just wish it could continue," said the 42-year-old, who broke his back when forced into an emergency landing when his paragliding wing collapsed.
"The feeling you get in the Velodrome, performing in front of 6,000 people, is something that you just don't want it to stop.
"It's an adrenaline rush that I've never experienced before.
"This whole Games was a dream of mine a long time ago and to come here and represent my country is a dream come true, but to actually be the first athlete there to win a medal for ParalympicsGB - that goes down in history.
"I'm progressing and getting quicker for Rio. I've got four years to prepare for that now so I'm already looking forward to that as well."
