The club has an experienced and very committed coaching team and has benefited from a number of parents who have now obtained a coaching qualifications. All are unpaid volunteers.

The coaching team is split so that a team of up to four coaches work with each training group:

WaldenJNR operates under Covid-Secure guidelines as per British Triathlon Federation and each training group is split into bubbles of 5 for the duration of training supported by a Wallace Crew of Community Activators who work with each bubble under the guidance of the Coaching team.

We are always looking for more helpers, so if you are interested in helping in anyway or coaching please contact Head Coach, Craig Dyce at
