Unlikely. A marathon is only ~26 miles and the best time is slightly
under 2:07. You would have to be the best long-distance runner in the
world to run 31 miles in 2:30.

Also, the amount of time and energy expended doing one sport does not
always neatly translate to the next. For example, in cycling, the
rough measure is that one running mile is equal to 4 cycling miles
(i.e. a marathon is equal to a century). However, the ratio of time
expenditure is not 1:4, but more like 1:3 or 1:2.5.

As a side note, skating, like cycling, lends itself to "cheating."
Unlike running, you can "coast" while skating. It takes constant
mental discipline to ensure that you are skating at a level that
provides a minimum aerobic workout. With running, as long as you only
have one foot on the ground at a time, you almost ensure yourself of
an aeorbic workout.
