I had the original T&F and Activision Olympic Decathlon on Atari computer. Both of them simulated running by wiggling the Atari stick back and forth. I cheesed my way through those games with a Trak-Ball with a turbo switch. I also had a decathlon game on our old TRS-80 computer which worked the same way and gave you funny messages and animations. The company that made it was none other than a very early Microsoft, just a few years after Bill got arrested for hot-rodding in the Albuquerque desert.
