It's up!! The April 2016 challenge is available
here.
ETYL, since you didn't log miles last month (which makes sense since you just got your bike yesterday), you will have to fill out the form. Your history will be imported, and moving forward, as long as you log a single mile, it will automatically add you moving forward.
Sorry for the delay everyone. Apparently my brain does not make the connection between April Fools and April 1st. :P
