I delay buy the 305 because I really want a gp watch that could report cadence . I consider the Polar rs800g3 , but it be more than twice the price and not as easy to use . I consider wait for the Forerunner 405 , but I be start a new season and do not want to change run log mid-season . so , I buy the 305 for less than $ 220 and add the foot pod -lrb- $ 80 -rrb- a week later . I plan on use the foot pod for indoor workout . my first run with it be on the treadmill . although the distance report differ slightly , it be fairly close without calibration . when I download the datum to my computer , I be surprise that it have record cadence ! but I pessimistically assume that it would not work when the gp be in use . my next run be outdoors , and to my surprise the 305 record cadence and gp distance at the same time ! I be even able to change the display to show cadence during my run . that be how easy it be to configure ! this watch greatly exceed my expectation ! I strongly recommend it for any serious endurance athlete !
