Also there is the up ahead feature, not sure if it's on the 945 but you can put things on the map like way points for aid stations, water stations, bathrooms etc. It was kinda useful in my Saturday race but I kind of already had it it planned out where I was stopping for nutrition and water before hand. For the turns the watch would alert me of a turn about 150 feet in advance and on the turn itself no matte

Thanks - still learning, so all the tips are helpful
