  We are SO excited to welcome you to our 7th annual Run With Coops, in support of the Cooper Robertson Foundation (CRF) and the SickKids Tuberous Sclerosis Complex (TSC) Clinic. This year, we are once again setting an ambitious goal: raising $1 more than last year, for a total of $55,641. Cooper Robertson, now 8 years old, was diagnosed with TSC at just 6 weeks old. With incredible support from family and friends, CRF was founded in 2019 as a registered Canadian charity. Since then, CRF has raised over $565,000 to support the SickKids TSC Clinic, helping fund care, research, and awareness for TSC. We are looking forward to coming together with the entire Cooper's Crew team, including family, friends, and kids, to walk, run, and wheel together. The Community Walk will take place on Sunday, October 4th, 2026, at Southward Community Park in Grimsby, with registration opening at 10:30 AM. Mark your calendars. We are making this year's celebration bigger and better than ever! We would love your

  help spreading the word. Share Run With Coops with your own crew of family and friends and help us reach our goal. Every bit of support, big or small, makes a meaningful difference. Together, we can do something truly amazing. The countdown is on. Let's go, Cooper's Crew! Thank you so much! Watch Cooper's Story below
