conv: Running uphill miles. A few months ago I could barely walk up a flight of stairs without having to catch my breath_comma_ but I bit the bullet and have been training. how has that been going for you? Wonderful! It's definitely hard work_comma_ but I continue on_comma_ even on the days I don't want to. Today I discovered I can now comfortably run an uphill mile and I feel very confident! that's amazing!
