The event itself

Colored map (green = 1h of waiting, yellow = 2, orange = 4, red = 8 )

In order to claim the gifts, you will need to unlock the location that holds them on the special event map. Depending on the location you choose you’ll have to wait between 1 to 8 hours to complete the unlock.

After you unlock a gift, you'll need to prove yourself a worthy citizen who does a little bit more than just logging in. During the event, the energy consumed and traveled distance will be logged, and a bit of each will be deducted when claiming a gift.

You can also use your currency to speed up your unlocks or recover some lost time.

You can add up to 3 locations in the unlock queue until day 4,390 [27 Nov 2019 23:59:59].

At the beginning of the event you’ll be able to pick to unlock any location as your starting point. Once your first location is unlocked, you'll only be able to choose from the locations which are directly linked to it. Use the 6 hours remaining to the start of the event to plan your path wisely.

A gift in an unlocked location can be claimed at any time until Day 4,391 [28 nov 2019 23:59:59], provided you have the required traveled kilometers and consumed energy. Kilometers and energy are counted starting Day 4,383 [20 Nov 2019 00:00:00] until Day 4,390 [27 Nov 2019 23:59:59]

PS. Recommended starting point is 24 Porta Delgada as it has perma bonus, access to both hemispheres and 3 routes to queue from the beginning of the event.
Actually the optimal route is pack related, acc (ground/air) related, rl time related so no general recommendations can be shared.
UPD. Miles and ff added
UPD2. Mind map added
