Summit Line vs MirRehab

Most training apps are built for the road and then have a mountain photo slapped on the icon. Summit Line is the other way around. It's built for trail and ultra from the ground up. This is for the runners counting vert instead of just miles, doing cutoff math in their heads at 2am, and trying to figure out how many carbs an hour they can actually keep down at mile 60. Tell it your goal race and it builds you a real plan. Week by week, workout by workout, worked back from race day and shaped around the fitness you've actually got right now. Your watch syncs your runs in and the plan adjusts, so it keeps up as you get fitter, or as work and life get in the way. Every morning you get a straight read on where you stand: fresh, flat, or digging yourself into a hole. No hype, no confetti for getting out of bed. Just the number and what it means for the run in front of you. And it handles the stuff that actually matters once the trail tips up: grade-adjusted pace so a climb can't lie to you, fueling and pacing set for your race instead of a road marathon, and your fitness, fatigue, and form tracked across the whole build. Free to start. Point it at a race and you'll have your plan today.
