Callison Running Club

The Cougar Running Club is back!!  Everyone from Kindergarten to 5th Grade is welcome to participate on Tuesday, Wednesday, and Thursday before school from 7:15-7:35.   As your child arrives at school he/she will follow the front sidewalk around to the running track on the south side of the building.  Teacher supervision will be provided.  All participating students will have enough time after Running Club to eat breakfast in their classroom.  In case we have to cancel due to rain or bad weather we will notify you by email the night before or by 6:30 a.m. the morning of our club.


All students participating in the Cougar Running Club will be expected to be on time and be present on these running days.  There will be incentives and prizes for those students who run the equivalent of one or more marathons over the course of six months.  Running before school is a great way to “wake up the brain” and prepare students for their day.


We would like to kick off Running Club on Tuesday October 6th.  The program will “run” through the end of March and conclude with a RRISD district celebration in April.   Please sign and detach the bottom portion of this form if your child is committed to joining our team. (Keep the top portion for yourself)
