Take a look at National Rail travel site for some MAN - EUS timings. Quite a few at 1hour 58.
Really? Between 05:00 and 13:00 on MAN -EUS I can see one service timed at 1hr 58min out of 25 services and in the reverse direction between 06:00 and 14:00 I can't find any at all (checking midweek with no advertised engineering works). So I'm not sure what your definition of quite a few is but it isn't the same as mine!
