The men’s team pursuit line-up of Tarling, Joe Holt, Will Roberts and Harvey McNaughton also laid down a marker ahead of the summer. The highly-rated Rhys Britton will return to contention for the summer too.
There were also medals in the para-tandem events – with Alex Pope and pilot Steffan Lloyd taking gold in the men’s kilo, while Nia Holt won a silver (sprint) and bronze (kilo) behind pilot Amy Cole. Both were new partnerships.
Another three medals went to Anna Morris – who won impressive silvers in the women’s individual pursuit and scratch race, before adding a bronze in the points race.
The junior doctor has taken a break from her medical career to focus on making this summer’s Commonwealth Games.
“There were times where we were doing 12/13 hour days,” Morris told BBC Sport Wales.
“When I got home I would think ‘what can I do?’ Even if it was just jumping on the bike for 20 minutes, doing a couple of hard efforts, at least my legs were getting some stimulus.
“I’d love to get there [to the Commonwealths] but you never know what your limit is. To have been able to make the progression to be in contention for selection, I’m well chuffed.”
