Distance / speed / averages are of course only relative to an individual and as such it is impossible to gauge what your maximum output is. Without going to ridiculous extremes like buying a powertap, a heart rate monitor can be a useful tool. I certainly wouldn't be hitting anything like maximum power or heart rate within a few minutes of leaving the house. You are obviously a fit individual and are capable of sustaining a high speed but I'm willing to bet you a drink [I'm in Cambridge several times during the year} that if you go at 50% for the first couple of miles, 75% for the next 3 then hit it for the last 7 you will average higher than you have managed before. You won't be damaging your health per se, but you will be tearing tiny muscle fibres which your body then has to repair instead of building and strengthening existing and new fibres.
On top of all that there is age related exercise damage but I'm not going there.......
