Intelligent running.
Aerithm brings clarity to each run, putting today’s effort in context and your progress in perspective.
01 / One run
Pace slowed as the road climbed and heart rate rose. The hill gives that harder stretch some context.
Recent runs pair a quicker pace with a lower heart rate. That’s a change worth exploring alongside the conditions you ran in.
One comparison opens into a wider pattern. Seeing this run among familiar efforts gives it a place in your story.
Those individual runs become 820 kilometres across 26 weeks. Progress takes shape through the days you keep returning.
Some weeks rise higher; others leave more room. The shape of your training tells more than any single peak.
Three in four runs began before noon. Across changing weeks, running found a familiar place in the day.
The hills, quieter weeks and early starts belong to one story. Together, they give you more to draw on than one standout run.
You arrive with every return, adjustment and ordinary run behind you. The next chapter starts here.
