It is that they are both operating at maximum performance levels and therefore the potential stress/rigors on the body are the same.
Trust me Standardbreds are working every bit as hard during a race as their TB counterparts.

It's irrelevant that they are both operating at maximum performance levels. A swimmer operates at maximum performance levels just like a runner, yet the wear and tear on a swimmer's body is far less than that of a runner. That's obviously an extreme example, but the analogy is correct.
