Q: How hard is the Arc Run 10K?

Arc Run is a 10K on a road course in Meriden, Connecticut. We don't have a verified elevation profile yet — check the organizer's course map for the climb breakdown.

Q: What should I wear for the Arc Run?

Race-day weather in Meriden can swing year over year, so dress for the forecast on the day. As a rule of thumb, dress for ~10°F warmer than the standing temperature once you start running.

Check the race-day weather forecast on this page closer to the date for a specific recommendation.
