Although Girmay is the sole African rider on this year's Tour, he thinks the world will soon see another fast-rising talent from Eritrea tackle cycling's premier event.
That man is 20-year-old Milkias Maekele, another powerful sprinter who won the men's road race at the Eritrean National Road Championships last month.
The Eritrean nationals are one of Africa's most hotly-contested road races, and the youngster from Asmara won in a dominant solo effort.
Girmay believes Maekele, who stands over six foot tall, has "huge potential".
"He has a strong mind for racing, a truly winning mentality.
"I am super happy for him for winning the national championships. He really deserved it as he raced very well."
Maekele, like Girmay, is a product of the As.Be.Co. team in Asmara, and his early performances saw him sign in 2025 for Germany's Team Bike Aid, a strong UCI Continental-level team with a history of supporting African riders.
After just one strong season, he was snapped up by the development squad of the top level Netcompany Ineos team which, beginning with its predecessor Team Sky, has established itself as one of the most dominant forces in modern cycling over the past 16 years.
Eritrea is Africa's most successful cycling nation, with four other men racing at the top level, including highly-rated Henok Mulubrhan (XDS Astana) and Natnael Tesfatsion (Movistar).
But Girmay remains the undeniable poster boy of African cycling and will burnish his reputation further if he can claim the Tour de France's green jersey for a second time.
Expect to see hundreds of Eritrean flags at each sprint finish over the coming weeks.
