As well as the various sports being placed into cohorts, performance directors in each sport have been asked to provide a list of athletes they would like to see back as a priority.
Efforts will then be made to get those names back up and running (or swimming) as soon as is safe and practical.
Those practical considerations involve not just the readiness of a training venue, but also the obvious need for medical supervision.
With social distancing and limits on the numbers of athletes and coaches, then training venues are quickly going to reach a new, low level of capacity.
Likewise, the level of medical support is also going to make the return of athletes a trickle at first, rather than a broad flow.
Those obstacles, insists Lewis, apply equally in England, even though the phased return of elite athletes over the border, has, in theory, happened at a quicker pace than in Wales.
“The safest way of reducing the risks is to come back slowly and with as small a number of athletes as possible,” he says.
“There needs to be medical oversight and there just aren’t that many sports medics in Wales to allow us to bring back lots of athletes.
“That is not a uniquely Welsh problem. It is the same in England. In ratio terms of medics to athletes, they are no better off than us.”
The guiding principle in the return of any athlete in any sport will continue to be mitigating the risks to public health.
That, insists, Jenkins, is something that athletes, coaches and officials are all agreed upon, even though he admits there may be some envious glances from budding young athletes who see others up ahead of them in the queue.
“Not everyone is going to go back straight away,” he says. “And there just isn’t the capacity.
“Also, we are not New Zealand. The infection rate is still too high. Athletes do not want to pick up the virus and take it back to a partner or a parent. Neither do coaches.
“The message is to be patient and keep safe. Everyone is working really hard collaboratively to get athletes back safely. Work with us and be patient. You will get back training and in safe circumstances.”
If that sounds a frustration for those athletes desperate to get back, then Lewis offers two further bits of advice.
Firstly, flat out hard graft on the training field has limited value if an athlete has no competition date ringed on their calendar.
And secondly, learning to be shrewd and resourceful by home-based training in the time of a global pandemic could turn out to be a very wise move.
“No-one knows how this is going to progress, but being really good at training from home might become a competitive advantage,” he says.
“If this pandemic sticks around for a while, the best way you prepare for Birmingham 2022 might not be training at an elite centre for a short period, but to get as good as you can be at training from home.”
