Using 2 apps at the same time?

[Really1]

Can I use the Nhs c25k app at the same time as having map my run track my speed and distance in the back ground? Or will turning one on turn the other off?

I used the get running app for the c25k and that ran with map my run. Could you set the two of them going when out for a walk one day and test it before you do a run?

I did find that map my run cut out loads though or took ages to load so that when I got home it would tell me I had run 0.2 miles
