So I know the entry standards for PJFT and can comfortably run the return in under 10:30. My issue is that the treadmill I have been training on is in Mph. Is this the case at Nuffield? What's the general order of business do they set the speed for you on the first leg and you adjust on the return or do they deal with everything? I know it's best effort but have also heard that if you touch the treadmill/grab at it you will fail? Is that the case even if you're literally just trying to increase the speed? Help appreciated!
