I get the Forerunner just in time to start the new year , and it have be a great motivational tool to keep I run on a regular basis . just see it on my desk make I want to go for a run !  i run a number of different route , and it be nice to be able to alter they on the fly to keep my distance fairly consistent . I have use it for walk , run and on my bike to check speed and distance , and it be easy to delete workout if you do not want bike or walk datum pollute you run log . if you be run in the dark you can press the power button briefly to turn on the -lrb- very nice golden -rrb- back light for about 15 seconds at a time .  the only problem that I have have be after change my weight setting the calorie counter seem to be a bit whack out - 216 calorie to run 6.27 mile in under a hour at 175 lb . do not seem quite correct . hopefully new firmware or a reset will correct it , but I 'll wait until after the pc log software be release before try to correct it .  it be easy to strap onto a bike that have a thick cyclometer or light mount on the handlebar , so I can not imagine buy the bike adapter at this point .  great product . have not be so happy on the bleeding edge since get my first generation ipod .
