Warframe

Sorry to say, but for this one you are Grounded! No flying of any kind!

This is cumulative and can get this through jogging, running, jumping, hell skip if you like because this one will take a little while. 2 to 6+ hrs. depending on how dedicated you are in getting it and frame speed. You will also get a notification every 10,000 meters.

There is no shortcut to get this because rubber banding does not work. I tried 2x. Once for 45 min and then an hr. and it did not go up at all until I started actually going to different areas.

The only thing that can make this go faster is by using a fast frame. The faster you go the faster you get 100,000 meters

So pull out those speed mods and start Running!

Speed frames

Loki 1.6
Ash 1.4
Vaunban 1.2
Nyx 1.1
Banshee, Emeber, Excal, Mag, Trinity & Volt 1.0

These are some of the faster frames without mods. Primes may have a slightly higher sprint base over normal frames.

Speed Mods

Armored Agility No upgrades 2.5% Sprint speed to frames base sprint and fully upgraded gives 15% to frames base speed. This mod also improves armor.
Rush No upgrades gives 5% Sprint speed to frames base sprint and fully upgraded gives 30% to frames base sprint.
Maglev this reduces friction when sliding and can help increase frames speed if you choose to do the run slide.
Sprint Boost This is an Aura and no upgrade gives 2.5% to base and fully upgraded gives 15% to base. This mod also stacks with other players for a whopping 60%

There are other mods that can improve your movement speed, these are some examples of mods you can add to your frame.

Happy Hunting Everyone!

This is tedious, but nothing you can't knock out very quickly. I would certainly suggest exploring the caves, getting your 100 beast kills, your 10 bounties, etc. before really worrying about your 100k meters. This will keep adding to your total as long as you are not flying across the map. I took my time doing these, taking the long routes, and I was well over 50K meters before I went to pop this. To get the last part of my achievement I simply walked out the back door of Cetus into the plains, pulled up the detailed map and set a waypoint at the top North. This is approximately 1500-1600 meters from you. Ran there and back to the doorway, dodging enemies and moving around bodies of water and knocked out 3000-3500 meters round trip. A bit of a grind but that's what achievement hunting is about sometimes. Happy Gaming :)
