I believe back in the day CDN could also help with libs due to maximum number of connection to same domain; but with http2 this issue went away.

I'd say you can forget half marathons for this year, as normally you can increase your running distance by 1km per week. So if you can't do 5 today, you won't be able to do 20 until 15 weeks later.
Just start small and keep it consistent no matter what - like running 1-2km per day NO MATTER WHAT (rain, snow, cold, w/e). Just do it.
