The televised competition was the final leg of the IAAF World Indoor Tour.
Many athletes were using the event as a warm-up for the World Indoor Championships, which get underway on Thursday in Birmingham.
King will be part of Great Britain’s team for that global competition. He took on a number of his rivals in Glasgow in the 60m hurdles.
The City of Plymouth athlete finished fourth in the race, behind Jamaica’s Ronald Levy, American’s Aries Merritt and GB team-mate Andy Pozzi. He clocked 7.74 seconds.
Meanwhile, Tamar Trotters’ Wilsmore took his opportunity on the big stage to set a new personal best in the men’s 1,500m.
Wilsmore finished eighth in a strong field in a time of 3:42.26 minutes. That was more than a second quicker than his previous best set in 2016. It also ranks him sixth in the UK.
The race in Glasgow was won by Kenya’s Bethwel Birgen in a season’s best time of 3:37.72. His team-mate Vincent Kibet was second.
Tank, who was running for Utah University, clocked 9:26.29 to finish ninth in the race. That was nearly three seconds faster than she had run before.
It was also the second time this year she had lowered her PB for the 3,000m. Prior to January her previous best was 9:39.88.
Tank is now ranked 15th in the senior women’s UK rankings at that distance and second under-23 athlete.
Also in America, Erme Valley Harriers’ Will Battershill finished seventh in his 3,000m race at the 2018 Ivy League Heptagonal Meet at Dartmouth College. Running for Harvard University, Battershill clocked 8:24.70.
