The USATF training chart gives a training time of 2.69 for a 10.2 competition time. So, 2.41 is definitely pushing the envelope of what might be considered “safe” unless you’re running fast enough to line up next to Bolt (I wish).
I’m not that much of an overspeed fan and won’t go anywhere near a towing apparatus. I did these two workouts in distance racing flats (~5 0z) on a slightly sloping but perfect surface in the parking lot of the local high school, which also has a rekortan track for the warmup and final sprint on the flat. You should do this on grass, but I don’t have one available without the surface imperfections that could easily sprain an ankle running at these paces.
