Ah, but did you spot me?
of course I did row 2 :)
Got an email with a link to a bunch of pictures from the Summit.
It's been in April the last 3 years in Olathe Ks. (Garmin HQ)
The developer summit has been held the week before the Garmin Marathon each of the past 3 years. While the dates have not been announced there is a good chance that it will follow the same schedule.
The 2020 marathon is set for April 18, 2020. The summit will likely be the Tuesday-Thursday before.
And the general schedule the last 3 years as been:
day 1: check-in/registration and evening social event at the hotel
day 2,3: general session in the mornings, breakouts in the afternoon (Garmin HQ), and an off site social event on day 2
I have normally registered in December - is the registration just not open yet - or is it being skipped this year?
