Feature request: count less than the full run's miles towards stroller miles

[dtran320]

Thanks so much for building Stroller Stats! I'm filing this as a feature request, and would be happy to submit a PR for review if this sounds like a feature that would be useful to others.

A few times so far, and very likely in the future, my wife and I will go for a run and switch off the stroller half-way through, or I'll do a run with the stroller, then drop it off at home before doing strides or a few more miles. For these runs, I feel bad claiming more miles than I actually did with the stroller, and would love to be able to do something like:

8-mile run, but only 5 with the stroller: First 6 #strollerstats or 6 miles #strollermiles and have it count as 5 or 6 miles towards stroller miles instead of the full 8 miles. We could of course make sure that the X in X #strollermiles doesn't exceed the length of the run so that you can't just say 42 #strollermiles on a 4-mile run.

Real-life example:

• 6.14 mile run, but only did 5.4 with the stroller
