The 5K running distance is like the gateway drug to marathons. It’s short, sweet and gives you a twinkle in your eye that just maybe, just maybe you could poooosssibly run a marathon. So why purchase a limited 5K training application that you have to abandon after your first race is done. Instead, get the new 5K To Marathon Runmeter GPS running app from Abvio (the geniuses behind Runmeter) to not only train for your first 5K, but also for your 10k, half and marathon when you feel the urge. So lace up the shoes, get off the couch and get going.
