hi --

i ride a road bike - about 25-30miles a time - i am pretty new - just been riding 3 months now...

i have signed up for a 300 mile in 5 days mixed on and off road trip which will be on hard tail mountain bikes through the desert...

my question is: if i train up so i can manage 50-60 miles a day on my road bike, doing some hills and stuff - will that be adequate training for doing same on a mountain bike on the trip do you think?

how different will it be?
all advice gratefully received :-)
