Fanny Packs

I have a quick question about the fanny packs. I’m doing a 10k in April and I was wondering if the fanny pack straps are long? I have not seen a fanny pack in person so I’m just curious. I’m a bigger girl so I need it to be Crossbody style. I wasn’t sure if it was going to fit across my chest. I went to Walmart today and tried different fanny packs on but the straps were not long enough and ended up choking me.🙈 🤣🤣. Thanks!!
