Stefano Battaglia set a new PR and exceeded his goal/VDOT projected time in Rome:

I just completed your 12 week half-marathon program. I’m very happy to tell you that I (we) achieved the goal to complete Rome half-marathon via Pacis in 1:42:50, better than planned. The course is a bit longer than 13.1 miles so the real timing for the correct half-marathon distance would have been 1:40:53 which makes a VDOT of 44.7 (good improvement).
