Can I add results through multiple results submission?
Currently, you can only submit results through one method of results submission. If you are using Strava you can add your multiple activities through this method, please find instructions here.
If you are using both Strava and Manual submission, you will need to only use the manual submission method otherwise it will overwrite your other submission. You'll then need to cumulate your time and distance in one submission. A new manual submission will overwrite your current results.
