You have studied to have the most efficient movement and found the way to push yourself beyond the physical limits. 

The feature that increases movement speed at certain levels are visible here but not on the sheet builder.

Mastery of Speed

Beginning when you choose this archetype at 3rd level, your movement speed increases by 15 feet and you can use a bonus action to take the dash, disengage or a singular attack. You movement then also increases at 7th level making the increase 20 feet, 10th level making the increase 25 feet, 15th level making the increase 30 feet, 18th level making the increase 35 feet

Evasion

At 7th level, your instinctive agility lets you dodge out of the way of certain area effects, such as a blue dragon’s lightning breath or a fireball spell. When you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.

Starting at 15th level, you learn to strike with your incredible speed behind making it so as long as you have moved 10 feet in a turn you can gain an additional d4 of damage equal to a tenth of the the movement you spent to the next melee weapon attack. This damage does not stack onto the next attacks.

At 18th level, you have learnt to recover faster than most. This allows you to use your second wind feature an additional amount of times equal to your dexterity modifier and the amount you heal by is increased by your dexterity modifier.
