However those only secure the top or bottom edge of the bib so it flops around and the full number is not always visible

If you care about your race photos being automatically identified thats not good

I initially thought that i might lose the magnets if i caught my finger on the bib but i think the most likely outcome would be that the corner of the bib would come out from between the magnets but the magnets would remain attached to the shirt

As some others have indicated it can be challenging to reposition your race bib once you have the magnets in place

I originally took my shirt off positioned the number and then attached the magnets before putting my shirt on

With a little work you can make small adjustments by sliding the magnets and the bib around

If that happens theres the possibility that one of the outer pieces will go flying while the inner piece will slide down the inside of your shirt and also get lost

Race bib numbers stayed for the whole race and never interfered with electronic recording
