You will need to use these abilities;
- Rapid Getaway
- Speed Freak
You are better off using melee consumers (as you start with 5/5 melee resources, in contrast to another resources for pistols, for example) to trigger Rapid Getaway, preferably one that is instant cast so you can spam sprint immediately after.
- Start towards the starting line and trigger Rapid Getaway
- As you pass the start line trigger Speed Freak and then get sprint up as soon as possible
- Keep running toward the finish line with just sprint
- Use Flicker at the last second to get you over the finish line.
Without using Flicker at the last second you won't make it, recasting anything during the run will take you out of sprint, and will slow you down.
