We used Subaru observations of A1689 (z=0.183) to derive an accurate, model-independent mass profile for the entire cluster, r≲ 2 Mpc/h, by combining magnification bias and distortion measurements. The projected mass profile steepens quickly with increasing radius, falling away to zero at r˜ 1.0 Mpc/h, well short of the anticipated virial radius. Our profile accurately matches onto the inner profile, r≲ 200{kpc}/h, derived from deep HST/ACS images. The combined ACS and Subaru information is well fitted by an NFW profile with virial mass, (1.93± 0.20)× 1015M_&sun;, and surprisingly high concentration, cvir=13.7+1.4-1.1, significantly larger than theoretically expected (cvir~= 4), corresponding to a relatively steep overall profile. These results are based on a reliable sample of background galaxies selected to be redder than the cluster E/S0 sequence. By including the faint blue galaxy population a much smaller distortion signal is found, demonstrating that blue cluster members significantly dilute the true signal for r≲ 400{kpc}/h. This contamination is likely to affect most weak lensing results to date.
