Ms Rodeka's coach, Squadrun's Kerry Suter, said she was a good example of the wider effects in a family of someone running.
"It's important for us to see our athletes training well but it's more important for us to see them having fun doing it.
"In a family setting that fun can be infectious and it's great that we've been able to scale the training to suit all three generations of Rodekas."
