The flash wore a red one and seemed to be fine. You can get them on ebay and amazon I see. Ha amazon.co.uk/dp/B000Q6V37W/ref=cm_sw_r_cp_apa_glt_fabc_GYXPY3FTM7E2KKHSDSQS :D
You're better with a belt that can hold a water bottle. Carrying a bottle when you run will impact your rhythm and can stop you getting into a good stride. Trainers wise, it's recommended that you get your gait analysed. But that said, I ran my quickest mile reps in army issue hi-tech silver shadows. You can get running visors just to keep the sun out your eyes, I wore one of these during London Marathon. They don't have a top so the heat can still escape. A buff as I previously mentioned is a cheap and versatile bit of kit, can be used as a hat, sweat band, wrist band to name but a few uses. Phone chest straps are getting more popular and they not as restrictive as arm bands. Download the couch to 5k app as a started or join a local running group, they cater for all levels. If you need any help give me a shout, I'm running and athletics coach. Although I do work more at the fundamental/kids level. Good luck.
my husband was into the park runs before covid and he found them great for motivation as it ranks you with other people. yeah, i have seen people with those water bottles that have a handle so you can hold it in your hand while you run.
Thanks for the cap recommendation. Do you think the one you linked would go well with sunglasses? Yea I won't go crazy with buying all these kit straight away, maybe after I build some momentum. In the past when I attempted to run ended giving up too early. I've heard about Parkrun, will definitely look into that. I actually live right besides Richmond Park, I'm sure that sort of thing will be a hotspot there.
I own a couple of pairs of Adidas Ultra Boost shoes - super comfy, I use them to walk in, but heard they're great for running in too. I think there are some pre-built in programmes on the Garmin Forerunner that trains you up from beginner when running. Hopefully they're good, otherwise might try the 'One You Couch to 5K' app - it's a free app, developed by the NHS. I need to look into water bottles - I've seen those hand held water bottle that is shaped around your hand to make it convenient to carry. I've seen those phone arm band things - need to look into them if I decide to take my phone with me. Thanks!
