One major consideration for running / cycling is wind reduction in software. True wireless earphones tend to have a large surface area and wind friction creates some very loud hissing noises that drown the audio. Sony WF-1000 series is excellent in this regard as it actually has a "wind reduction" mode. The latest mark4 model is beyond your budget, but the outgoing mark3 is going at £94 on amazon, even cheaper 2nd hand. They are large buds so best to go with foam tips for extra security.
edit: I would add that these are best in class in terms of true wireless earphones audio quality if you like a balance to warm sound profile in your music
