And you are right to decide that this type of commute is not for you right off the bat because I can tell you , as someone who did a 2 hour (at least, depending on traffic and weather) Commute each way for many years, it becomes a life of its own.... I had to modify my work schedule, the girls' school schedules, arrange for my other child to be cared for around this 200 mile round trip commute each day ...it is daunting and is not a "let's see how it goes" type of committment. It was worth it for us but definitely not for most folks...
That said, I'm sad her gymnastics didn't end on your daughter's terms... but that happened to my youngest with an injury, and I can tell you , she did thrive in other activities and with her friends , after she left the sport so there is life after gymnastics.
