The cyclists were among a group of five struck by a blue Hyundai Accent at about 6:20am on August 27 in Palmerston. Ms Lee, 32, died at the scene, while Mr Riethmuller, 39, died days later in hospital. Members of the public, including an off-duty nurse and police officer, assisted the injured cyclists before emergency services arrived.
The pair were members of the Canberra Bilbys Triathlon Club. Club secretary Katie Binstock said the memorial ride was organised to remember Ms Lee and Mr Riethmuller and to support those grieving. 'We knew the community was hurting, and we thought it would be a nice way for them to come out and start the healing process,' Ms Binstock said. 'And also, to get together and talk to each other and to hopefully get a bit of courage back to ride on the road as well.'
Ms Binstock said that in the first week after the crash, only one person showed up for their weekly morning ride, and there had been 'hesitancy' to return to the road. Speaking to ABC 666 Canberra on the morning of the crash, she recalled being called to the scene. 'It was a shock. They didn't tell me precisely what had happened, probably because they couldn't find the words. So I didn't quite know what to expect,' she said. 'We go out expecting that sometimes things like punctures and minor things will happen, but I didn't expect this to be what had happened.'
The driver of the vehicle, a 40-year-old woman, was assisting police with enquiries. No charges have been laid.
