Play jump animation whilst run animation is playing using Loop Time

Hi guys,

So I've made a non humanoid 3D character - starting off with a simple run loop and jump animation.

So I've setup the animator as Entry > run then jump is in there, so I can refer to it in the script

Run is setup frame 0-20 with Loop Time ticked.
Jump is setup frame 20-40 without Loop Time ticked.

Below is my amateur code :/ got to start somewhere!

 #pragma strict
 
 var anim : Animator;
 
 function Start() {
     anim = GetComponent.<Animator>();
 }
 
 
 function Update () {
 
     transform.Translate(Vector3.forward * Time.deltaTime * 10);
     
     if(Input.GetKeyDown(KeyCode.Space)){
         anim.Play("jump");
         transform.Translate(Vector3.up * Time.deltaTime * 10);
     } else {
         anim.Play("run");
     }
          
 }

So the problem is the run animation is playing on a loop (woohoo), which is fine, but when I hit the space bar to make the character jump it only plays the jump animation for a split second before returning to the run animation. Anyway to play the jump animation till the end before returning to the run loop?

Many Thanks
