The new science of injury free running has you landing on the forefoot there by using yourself as a shock absorber,, running on grass is very bad for your knees causes shin splints and other bad things lol.
Oh OK, all those real sportspeople running laps as preseason training in team games, and playing all season on grass, artificial and real, must be in for a bad injury time.

Let alone the track and field athletes who would boycott an event run on asphalt.
Trust me, the majority of people running on MUPs wouldn't have a clue about the science of running, much less about running on their forefoot, a trend that started with athletics and the use of spikes on running shoes.
