First time hitting 25 miles

I see people posting their first time cycling 50 miles and I’m jealous so I thought I would post my first 25 miles. I’m new to cycling (35 year old male) with a 2nd hand Schwinn Phocus from marketplace. I threw some clipless pedals on, a new saddle and have been attempting to fit the bike according to YouTube videos (I know I should go to a bike shop). I have done some quick 2 miles rides here and there but have been really wanting to actually cycle. I have 7 rides in the past 2 weeks that were 10 miles and then a 15 mile ride. My overall pace was gradually increasing every ride from 10.2 mph to 13.3 mph. Then I decided to really push myself and go for a 25 mile ride today. My pace was a bit slower and some of that was the last few miles were really getting to me. I have only been really riding for a few weeks now and haven’t even purchased bibs yet, which my undercarriage is screaming for and I need another water bottle cage since 1 water bottle is not doing it in the summer heat. But those will be purchased later today. After looking at some posts about 50 mile rides and their times I know I’m not setting any records or anything but I just wanted to share this small accomplishment and see if anyone had any suggestions or recommendations.
