I know that this may sound droll to some/many/most? - but I have only just discovered how to use the manual "lap pace" on my Garmin FR220. I like to follow Jack Daniel's training plans using his calculator to tell me the appropriate pace I should be running at for different types of runs ( according to my current fitness level as revealed by my latest 5k PB) . His tempo paced intervals have me running 4 minute, 6 minute, 12 minute running intervals with 1 minute easy running/rest inbetween. I am supposed to run these at a 6:15 mins per Klm pace but have never been able to satisfactorily assess whether I am running at this pace while actually running. NOW - I realise that if I set "lap pace" as one of the data sets on my watch (along with "average pace" and time) , and by pushing the lap button at the start and end of each run segment , I can see the average pace I am running during the segment. DUH!!!!
