Inspiring and it's great to aim high. My goal is to run the Melbourne Marathon this year. I have already paid my entry fee which is motivation enough as it is bloody expensive. I track my progress in Strava ny mapping my training runs and increasing my runs by 1 km each week. I can also see if my speed has improved for specific sections of my run. It is great to see progress. Good luck with your goals and yes I will buy you underwear.
