No racing is just a standard clause in insurance. look in your motor policy, you'll see the same. This applies even if your car is a Caterham 7 / Porsche 911 with full cage and 6 point safety harnesses.
If you write off your bike when covered in race numbers etc and you are in too much of a mess to say "I was just training" then it may be excluded, but if you are out on a ride your statement "I was just out for a ride" is good enough. They won't care.
