How can I find the mean distance travelled on each day of the week over a certain period of time. I have the distance travelled for each day but need to find the mean for each week day.

check out splitapply. You may need to change the format of your data, but it does exactly what you want:
G = findgroups(Day);
mean_dist = splitapply(@mean,distance,G);
