RW Marathon Schedules For Garmin

I've downloaded a RW marathon schedule from this site and imported it into the Garmin Training Center (version3.5.3). It's clearly visible in my calendar and I have synced it to my 310xt without difficulty.

This morning I set about following the workout on my Garmin. However, the screen simply shows the target distance and heart rate. The distance remains constant on the screen. I would have expected it to count down as I add miles to my run else how am I supposed to know how far I've gone? Am I meant to plot my route first with mapmyrun or similar thereby negating the point of a gps enabled device?
Cheers
Folks

cant you just solve the problem by altering the data fields you have visible?

Thanks for your reply Crazytown Emperor. I tried again this morning. Whereas I can normally scroll thru data screens, when using a "workout" no scrolling is possible. Neither can I alter the visible data fields as I have when doing a "regular" run.

Are these workouts just meant as an on-screen reminder with no built in GPS functionality?

@Keith Allen 5 - read page 15 ("Workouts") of the manual. It explains it all, including how to scroll through data screens, all when in "Workout" mode.

Booyakasha! Cheers Intermanaut
