Johnston and his crew were not selected for the squad at the 2010 Winter Olympics in Vancouver, despite winning the trial races in Germany and Switzerland in 2009.
This program had huge success finishing before the Youth games ranked 1 -2 - 3 in the females and 1 -3 - 4 in the males in their series of races.
Johnston has been the head coach through a difficult time from 2017 to 2019, but over those two seasons on the World Cup, Lamin Deen, Brad Hall, and Mica McNeil have all gained their best ever results with their teams.
Due to funding, Johnston was released by British Bobsleigh in July 2019 but was re-employed in October as a Consultant Coach and Manager, hoping to carry on the work that has already been done with the senior three pilots.
On a side note, his youngest son[clarification needed] has been selected for the 3rd Youth Programme, making him the fourth member of the Johnston family to represent Great Britain.
