Muppet, thanks for reminding me of "Alf Tupper - tough of the track".
Like you I remember the cartoon but not the comic.
I seem to recall the storyline being similar each week, involving our hero Alf, being forced to spend the night prior to the "big race" doing some urgent welding repair in his workshop and then, possibly due to the lack of decent public transport in his locality, having to run all the way to the track meeting, arriving with seconds to spare, and going on to win the race!!
What a guy!!
Now what was the comic?

C-flat.
