Okay, I've finally gotten it done. I e-mailed you the model.
It was extremely hard to do, and didn't turn out perfect by any means. Lots of vertices were broken, leaving holes in the model. There was no symmetry in the body either, which made repairing the holes very hard. You should probably redo the model. However, the animations work, and they'll certainly work in your game.
You requested only a run animation, but I thought a few more might be useful. I've included basic movements and jumping, plus the same animations holding a pistol. You'll need to glue it to the model yourself. However, as the model has no limbs save for the root limb, that might be a challenge.
Here are the animations. I included them in the e-mail.
Frames Animation sequence
0 - 79 "idle"
80 - 129 "death_backward"
130 - 185 "jump"
186 - 219 "pain_back"
220 - 269 "pistol_death_backward"
270 - 349 "pistol_idle"
350 - 405 "pistol_jump"
406 - 439 "pistol_pain_back"
440 - 464 "pistol_run"
465 - 495 "pistol_walk"
496 - 535 "pistol_walk_left"
536 - 575 "pistol_walk_right"
576 - 600 "run"
601 - 631 "walk"
632 - 671 "walk_left"
672 - 711 "walk_right"
Oh, one thing. I forgot to include the yago.bmp texture in the RAR file. Just copy it to the same place and it should work just fine.
Good luck with the game.
Come see the WIP!
