In 2009, Hall was the youngest skipper of a yacht that won a round-the-world yacht race, while Norris is the youngest person to reach both the summit of Mt Everest and the North Pole.

TTNG said the conference had attracted 515 delegates with 327 of its agent members set to attend.

Gary Lewis, chief executive, said: “We have selected three extremely highly regarded speakers for this year’s event, all of whom have so much experience to share with our members and reinforce, perfectly, the conference theme.

“They have all been selected on their ability to motivate and inspire, and will share strategies that will help members develop their own teams and drive strong performance in the face of change, disruption and uncertainty.”
