Do you like to run for a really long time? If you answered yes, then this build is for you. This is the Cross-Country runner of Tamriel. It can be used for discovering locations fast or racing your friend.
I picked a wood elf as they have the highest stamina recovery as the game doesn't want a free sprint cost. We will make it cost almost nothing, but having high stamina and stamina recovery will be important.

The abilities that will be used are:
Bar One:
Bull Netch--Gives stamina over time as well as major brutality
Deceptive Predator--Gives major expedition without buffing anyone and also increases stamina recovery by 20% while active
Enchanted Growth--An ability that heals and gives 10% magicka and stamina recovery while active
Bursting Vines--Oh, your friend happened to get ahead of you, not a problem, because you can travel right to them for 22m
Whirling Blades--Used to take out some enemies as an aoe but not to be used in a race
Bar Two:
Bull Netch--Same as above
Deceptive Predator--Same as above
Rapid Strikes--Quick single target attack that shouldn't be used in a race but only for travel
Bursting Vines--Same as above
Gripping Shards--Stun the annoying enemies in the way
Ultimate:
The Ultimate on both bars will be werewolf ultimate because it gives 15% stamina recovery while slotted.
The gear that will be used is the prisoner set and the darkstride set. I chose prisoner over Fiord's Legacy because this is an endurance and not a straight speed build. Prisoner and darkstride both give 50% reduced sprinting and prisoner gives 1000 magicka per second while sprinting.

Darkstride:
2 items: Stamina
3 items: Stamina
4 items: Stamina Recovery
5 items: Reduces Sprint and Sneak cost by 50%

Prisoner:
2 items: Stamina
3 items: Stamina Recovery
4 items: Stamina Recovery
5 items: 50% reduced cost of sprinting and restore 1000 magicka every 1 second

All Armor will be Well-Fitted for reduced sprint and roll cost and will be medium for more sprint speed, and it will also need to be stamina enchanted. All rings should be stamina recovery enchanted.

Chest: Darkstride
Feet: Darkstride
Waist: Darkstride
Hands: Darkstride
Legs: Darkstride
Head: Engine Guardian
Shoulders: Engine Guardian
Swords: Prisoner
Swords: Prisoner
Neck: Prisoner
Ring: Prisoner
Ring: Prisoner

Champion Points:
Make sure the reduced cost of sprinting is all the way up and the stamina recovery is all the way up. Also, put about 20 points in magicka recovery to get the Windrunner passive.
Food: All stamina recovery

Time for a Run.
