Of course you could get the jogger to get into rollerskating instead and use encoders on the wheels. Just know that the general conclusion is that it is the wrong sensory input for the task :) If you still want to pursue it, just google 'accelerometer velocity' - there are some existing implementations and the sensor's accuracy of course does matter.

GPS, on the other hand, is horrible at instantaneous events. You're better off with a GPS since the inaccuracy tends to be relatively low and for calculations actually gets lower over distance and time (although you're really measuring the average speed).

Now consider the inaccuracies of the accelerometer, the integration methods and a host of other things (starting with the jogger not being an ideal directional vector, but rather something that's going to make the accelerometer axes outputs bounce around pretty wildly), and the answer is typically 'yes, but over small time periods, with a known reference velocity (usually: standing still), and with a fairly big and accumulating error (drift)'. So now consider how you get speed from acceleration - by integrating over time.

Consider what an accelerometer actually measures acceleration.
