A taxi driver who hit and killed a cyclist after "falling asleep" at the wheel following a 13-hour shift has been jailed for three years.
Craig Gough, 36, crashed into former soldier Jack Berry, 26, on the A48 near Cowbridge, Vale of Glamorgan.
Gough, of Colwinston, Vale of Glamorgan, previously admitted causing death by dangerous driving.
Cardiff Crown Court heard Mr Berry would have been visible for 15 seconds before the crash in October last year.
Mr Berry's father John said his son was "just an incredibly special boy. He was a great husband to Lu, a great son to us, a great brother to Charlie".
Two other cyclists were injured in the crash, and witnesses described them as "really well lit".
All three were wearing reflective clothing and safety equipment as they travelled in single file, with Mr Berry at the back, the court heard.
The other cyclists said they had suffered from long-term distress after the crash.
Judge Eleri Rees said "an obvious conclusion" was "that [Gough] did indeed fall asleep" and he had worked for a "grossly excessive time".
Mr Berry spent six months in the Army and completed a tour of Afghanistan.
After working in financial services, he dreamed of starting his own restaurant business.
His father said: "Obviously we are heartbroken. But from day one, we were absolutely adamant that we would try not to get angry. We would stay strong."
With a combination of savings and fundraising, his family has built a school in Fiji, where Mr Berry's wife Luisa was born.
"Jack is no longer here, but he is still going to help a lot of people," John Berry said.
"In all this unbelievable heartbreak and grief, we were determined we'd get as many positives out of it as we could.
"This is not the end. It's really the beginning."
