How to report errors in training plans?

The first training plan I've come to use, the Marathon Level I by Full Potential, has some errors. Does anyone how I report these to get them fixed?

I know can fix each workout in my own calendar, but obviously many people are going to have the same issue.

I wonder what kind of errors you want to report. I have got some translation errors in the calendar from GCM...

Not sure about your translation errors, but just appears to be a mistake by whoever initially created the training plans.

In the "Marathon Level I" training plan for instance, W10D3 Threshold Run says "Run in Z4, threshold pace, 5 minutes. Run in Z2, recovery pace, 90 seconds. Repeat 4 times.

However the actual workout has got the Z4 run for minutes repeated 4 times consecutively, and then a single Z2 recovery of 90 seconds. This is obviously very different.

In the same training plan, W14D7 has a similar problem.

And again in the same training plan, a slightly different problem. W10D7 says run a half marathon and specifies a length of 21.08km. A half marathon is 21.10km or preferably 21097m. I know its only 200 metres you might as well get it correct!
