Spectator guide

It's a point-to-point-ish course, so spectating means picking one or two spots and committing.

Key points on course

• Start — 42.229, -71.523
• Finish — 42.350, -71.079
• Expo — 42.347, -71.081

Phones die and cell networks jam near big finish lines, so agree on a meeting point before the start. That one habit saves the day every time.
