Awning poles elastic perished

We havent used our Sunncamp magnum 260 porch awning for about a year . However  we needed it this weekend as our son was coming with us and we have a two berth. Upon unpacking the pole all the elastics on all 3 poles  have gone. I could understand one going but all 3. The awning was puit away dry last time. Good job we had also took his tent( we wanted to keep that dry as whe was going to Leeds festival day after arrival home) but had to use it.

I'm going to try & restring them does anyone have experience of doing it. Also counting the sections of pole there is a odd number so not sure how may sections to each complete pole. If anyone can help its a Sunncamp Magnum 360 porch awning
