How Can My Garmin 305 Help Me Train For A Sub 3hr Marathon?
I know this watch has an abundance of features, but i fear im wasting them. For an example . . .if i go for a 5 mile run i want the watch to tell me if im on schedule for a sub 3hr finish? How do i do this?








Read the instructions, it is too much for someone to copy down here or to have the interest in copying it down since you can read how with the instruction. Look at working out with the virtual partner, you can set it up distance (5 miles) and time (34:20). It should show a pace of 6:52. In this mode it will show if you are ahead of behind pace and how far. You can also set pace alerts so that the watch chimes when you are off pace. It might even do some other things, I only have a 301. Good luck!
