With her being 2-3 years old she should have no problem with you on a run. I am not sure how far you run every day but I would take her with you and see how she does. We once took our female B on a 22 km hike, she was a tired puppy after that one and the day after the hike too! Good luck with the Fetching game…..my B's do not really like to fetch, and will only bring back the toy if they really feel like it.
