Training Calendar, More Challenges Diversity, iOS Widget

Dear Strava,

The training calendar displaying our activities history is pretty plain and lacking some usefull informations. For reference, Endomondo is much more versatile and complete. Is the Strava Premium version more complete? Or any plans to improve this? The Sports Tracker Activities Calendar is also very cool in design.

I always see monthly challenges for 10k running... how about 5k running challenges? And always the focus either in Biking or Running. How about adding Walking challenges too?

The Strava iOS widget is also very plain... and it shows only the main activity (running OR biking)... how about improving it, any plans? Again, Endomondo's iOS Widget is much richer showing three types (running, biking, walking) and much more data, Strava Widget should look something similar, I would suggest.

Kind regards,
