Follow-up on my experience doing the actual race.
Summary:
I’ve used navigation with multiple waypoints during the entire 16 hours of the race
After some considerable effort I managed to have the right set of waypoints at exact distances where aid stations were supposed to be on the race course. Two of the aid stations were visited during the race 2 times each. Other aid stations were visited once. Once I’ve had the correct preview of the waypoints in the app (see the picture above), the navigation was working mostly correctly, as expected during the race.
The battery usage was exceptional - better than expected despite using navigation for the entire 16 hours and looking at the map and elevation profile most of the time. My Race 1 watch used only 27% of the battery in 16 hours, which makes the projected battery life over 59 hours. I used the High Contrast map theme. Also, I used an external HR sensor. I ran two S+ apps
I was using Climb guidance 2.0 with all aid stations on the profile. That worked generally well and was useful. I could track both the remaining distance to each next aid station and the remaining ascent/descent. However I’ve run into two known issues that I’ll mention below. Both of these issues have already been reported in separate threads.
[Issue 1]: The navigation route reversed twice during the race - both times when reaching the ends of out-and-back sections. This is something I’ve actually anticipated based on my prior experience - see https://forum.suunto.com/topic/12994/suunto-navigation-tendency-to-auto-reverse-route-when-it-shouldn-t.-bug-or-misguided-feature

This resulted in the watch showing incorrect profile and incorrect distance to next aid station until I was out of out-and-back sections.
[Issue 2] The climb guidance profile could not be zoomed to the desired level of details at the end of the route. This is covered by https://forum.suunto.com/topic/13601/climb-guidance-2.0-issue-not-all-zoom-levels-are-available-at-the-end-of-the-route-see-picture.
This was especially bad considering the 100 km distance.
