This fall, St. Francis DeSales High School students will head back to class without a beloved teacher and coach.
Bob Lennon was killed September 15, 2013 when he was struck by a car as he rode his bike on Miller-Paul Road in Delaware County.
The driver, Katy Paul, didn't stop. She eventually pleaded guilty to involuntary manslaughter and fleeing the scene of an accident. She was sentenced to 4.5 years in prison.
On Saturday, nearly 600 runners and walkers came out to Hoff Woods Park for the first Lennon Loop 5K.
Lennon was a science teacher and a cross country coach for more than 40 years.
"He really thought that running is what brings people together and the fact that we're just running all together as a community for him, just makes it so much better," said former student Kristin Faulkner.
Lennon's absence left a void in the classroom and on the course.
"When we lost Bob, that was clearly in evidence by the love and support of the remaining faculty members, his family and the greater St. Francis DeSales High School family," said principal Dan Garrick.
Former students from Rhode Island to Alaska came out to show their support.
Proceeds from the Lennon Loop 5K will go to the newly established St. Francis DeSales High School Bob Lennon Memorial Scholarship.
