Hi. I primarily use my Forerunner 645. However, when I sent it for repairs at one point, I got a good deal on a used 735xl to use for a few weeks, and soon I'll give it to my daughter. In the meanwhile, I'm planning on doing the Marine Corps Marathon Virtual Duathlon (5k Run, 20.4k Ride, 5K Run). I picked out a route around my neighborhood, but wanted to see if I can do this as a course, with the route showing on the 735. When I use the course creation on Connect, I can only pick bicycle or running. Would a Course work in the multisport mode? Which type of course should I select, "Other?" I tried searching the manual, but didn't see anything covering this topic. Thanks for any information.
