For Endomondo users (at least for me), there appears to be a huge problem when entering a new workout on the website. I have, on more than a dozen occasions, entered a new spin workout on my personal page only to have Endomondo not recognize the mileage in the weekly, monthly or yearly totals. This is hit or miss – sometimes the workout will be recognized in the totals, sometimes it won’t.
To work around this, whenever I enter a new workout, I do it through the program on my phone. Problem solved.
