I am a father of a third grader and a former Div. I runner. We enrolled our daughter in Girls on The Run, a 3-5 grade running club before school. The goal is to complete a 5k 2 months after the club started.
I notice it is mostly 3rd graders and after two weeks they do a 2.5 mile run. Most of the girls walk and several complain alot, especially when they hit the hills.
I feel that this is too much running for an 8 year old. I only raced 1.5 miles in middle school. I don't want my daughter to hate running since I can tell she is pretty fast.
