I did two runs this week but when I received my run summary email this morning it said 0 miles run. I just logged in and can see both runs were imported from Strava showing 14 miles in total run.
It looks like your two runs last week were synced today, which is why they didn’t make it in the weekly run report 
Unfortunately, we don’t have access yet to Strava’s Push API, so you’ll have to click sync on Smashrun in order to grab your runs.
