Have you heard of Team Hoyt? They are a father/son team who have completed 65+ marathons, 225+ triathlons, 6 Ironman triathlons & many many more races. The amazing thing is that the son is in a wheelchair. The father pushes him, carries him, bikes with him & pulls him in a boat, in order to finish the race. They are an amazing team.
My Aunt just sent me this video. Watch and be inspired.
