I dont know what the 5k one is like. But was worth the money for me. Im the slackest laziest person around and ive been out for a walk every day this week. So its working for me. If you put tracking on it gives you some really detailed stats of your run. Overall distance and time. Your average speed plus it tracks you the whole way so you can see the exact speed you were goibg for every metre of the walk and where you sped up and what bits you slows at and what track played at that time and where you were at. I can make my profile public and you can see (not sure how much it shows other ppl tho)
