Bike fitting Inverness feedback

Some feedback on my bike fit back on May, previously after 10-15 miles i got cramp in my feet, then after 20 sore back so anything over 30 miles was murder.
However since the fit i completed the Isle of Mull sportive 90 miles with no issues other than my legs gave up but that was down to me.
Also i now quite often do 40-50 miles at a time with no issues and really enjoy cycling.
At the end of this month i have heading down to Birmingham for a 185 mile charity cycle for Stand up to Cancer with BT ( Tour der BT 2017) .
So what i am saying is thanks for the fit it made a massive difference i was not convinced it would be has been amazing and also I now know how i need to set up my bike for comfort etc. thanks Drew
