My 20th birthday is on April first, my goal is to run my first ever Marathon before then.

I will resolve yes if I have run 42.2 kilometres before the beginning of April. How long my run takes doesn't matter (although my goal is under 5 hours). I'll use Strava to track my run and show that I have really run a marathon. If Strava stops working I'll use a different app.

Some information about my running ability:

Since 2018 I've tracked about 95% of my runs on Strava, here is my Strava profile:

A short summary of my profile:

I have never run a marathon before but done two half marathons. My personal best for a half marathon is 2:15:01. I have walked 36 kilometres before. Since September 2018 I have run 935 kilometres during 194 runs.

I will not bet no on this market and won't ever sell any of my yes shares.
