This was just a day after the curtains came down on the Commonwealth Games and two days after the end of World Under-20 championships.
But despite failures in the country's disciplines, the Kenyan stars came back with bountiful lessons.
From Birmingham, the next edition of the Commonwealth Games will take place in 2026, in Melbourne and regional Victoria, the city that last hosted the competitions in 2006.
Kenya was ranked 13th with 21 medals - six gold, five silver and ten bronze medals, an improvement from 2010 Gold Coast where the country was placed 14th with 17 medals - four gold, seven silver and six bronze medals.
It's now time to take a critical assessment of athletes' form ahead of races. A number of athletes could not deliver medals for the country, especially at the World Championships because of injuries.
For example, the 2019 1500m world champion Timothy Cheruiyot lost his title to Great Britain's Jack Wightman in Oregon.
Tactical questions
Abel Kipsang was a world leader as he lined up alongside Timothy Cheruiyot at the Oregon 2022 World 1500m, a tactical blunder that denied the top guns a medal at the global show.
Birir also raised concerns over fitness and level of preparedness, noting that a number of athletes, such as 5000m star Nicholas Kimeli and his 1500m compatriot Abel Kipsang, went to the World Championships as world leaders, but could not finish in podium places.
He says Kenya should change its tactics in future races.
"The rest of the world has known our secret. They know that we win in fast-paced races and they decided to be tactical by maintaining a slow pace and finishing fast," the former star pointed out.
Focus on men's team too
A look into the list of gold medal winners reveals Kenyan women were way above their male counterparts.
At the 2022 World Championships for instance, six out ten medallists were women.
The women medallists were Faith Kipyegon (1500m gold), Beatrice Chebet (5000m silver), Hellen Obiri (10,000m silver), Judith Jeptum (marathon silver), Margaret Chelimo (10,000m bronze) and Mary Moraa (800m bronze).
And at the Cali World Under-20 championships, six women and four men secured medals that placed Kenya fourth on the medal table. Three men and a similar number of women brought home gold at the Birmingham Club Games.
At the 2019 World Championships, three women and two men won gold medals for Kenya.
Doping
A dark cloud of doping allegations hung over the country's mission at the global shows. Top marathoners - Lawrence Cherono and Philemon Kacheran were provisionally suspended after testing positive for banned substances.
Cherono, an Olympian and a former Chicago marathon winner, had already travelled to Oregon, ready for the marathon race when the Athletics Integrity Unity (AIU) made public his positive test.
Kacheran, on the other hand, was preparing to fly the Kenyan flag at the Commonwealth Games respectively.
"There is no better time to address the elephant in the room which is hindering our success than now," The Veteran Athletes Association of Kenya said in a statement.
