Mr Hall was killed in a collision with a car on the Monaro Highway last week while competing in the inaugural Indian Pacific Wheel Race, a solo endurance cycle from Fremantle to Sydney.

Hundreds of cyclists gathered to observe a minute silence at 6.22am, the time it's believed Mr Hall was killed.

Mr Hall wasn't known to many of those gathered, but the crowd shared admiration for his passion and feats in endurance cycling.

British deputy high commissioner Ingrid Southworth laid a wreath at the memorial, two bicycle wheels stacked high.

"I know that his family have been deeply touched by all of the tributes across the world [...] particularly here in Australia," Ms Southworth said.

Mr Hall's girlfriend, Anna Haslock, said Mike had been a hero; fiercely independent but vulnerable and complex.

"The best tribute we can pay to Mike is to ride our bikes as often as possible," Ms Southworth said on behalf of Ms Haslock.

She said cyclists should strive for the day it was safe to share the roads.

Mike's mother, Pat Hall, said many amazing tributes had helped with her grief.

"I know to you he was a hero, but to me he was just my baby," Ms Hall said through Ms Southworth.

"All he was doing was his thing. Every time you set out on your bike: ride safe, ride strong and ride with Mike in your heart."

Fellow IPWR competitor Sebastian Dunne said Mr Hall had made millions of other lives richer by founding a European endurance cycling tournament.

He repeated the words of Mike Hall to the crowd: "It's okay to cry, just make sure you do it on the bike."
