This thread from 2009 might be of interest.
I just took this test again, and my reading speed was 370wpm and 100% comprehension. In 2009 it was 411wpm and again, 100%.
So I'm around 400wpm, what that web site calls an 'auditory' reader, which seems right to me.
So a 350 page novel, being around 150,000 words takes me about 6 hours to read. Hmm... that seems a little slower than my reading record shows. So perhaps when reading my books instead of their test text I'm a bit faster.
