I have just completed wk5 & feeling very pleased with my self .I don't know much about these garmin watches, I know they give you info on your runs etc.. I'm not up on stuff like this , would you get one if I have I phone with running apps on ? Haven't used apps yet coz I'm . Just concentrating on doing what Laura says and getting through it , but soon I want to see how fast I run & how far I go & all that stuff . I'm no good with maps or anything and understanding all this 5k stuff in certain times also whats all this bpm? Hope I don't sound really thick lol . Thanks for any advice.
