Annual charity run held since 1999

+++ Update +++

We are sad to announce that MS2S 2021 cannot take place as planned – the Covid-19 situation in Mongolia, with quarantine and travel restrictions, makes it impossible. EcoLeap needs your support – join the 2nd Virtual Run instead! Read our update here and share our flyer. We hope that many of you support our charity initiatives by joining the Virtual Run!

Happy running and stay tuned!
