Griffith also secured county and regional titles and placed fourth in the Class 4A state championships.
"Sometimes, athletes are really talented, and then sometimes, you have one that work really hard," Kramer said. "When you put those two together, its an incredibly powerful combination. And I think from the very beginning, Isabel had both of those things."
Griffith shined again in the this spring, grabbing county championships in both the 1,600 and 3,200.
"She is the best female athlete I have coached in 16 years," Boyle explained.
Boyle considered her performance in the state championships, where she took second in the 3,200 and third in the 1,600, even more impressive.
She posted another stellar time in the 3,200 (10:59.46) despite winds gusting 20-to-30 miles per hour.
"(The 3,200) was the best I have ever seen Isabel perform," Boyle said "I was amazed that she broke 11:00 in those conditions.
"This spring, she didn't lose a race in the mile or the 2-mile until the state championships,'" he added.
In addition to her talent, the Dulaney coaching staff loves Griffith's leadership abilities.
She was co-captain of the cross country, indoor and outdoor track teams.
"She is very motivating for the other girls on the team," Kramer said. "She knows other people's personal records. She is incredibly encouraging. I hear pep talks from her before races. She loves running on the relays, like the 3,200 meter relay, because she is able to work with her teammates."
