Don't know the reasons for your dread, but sounds like laziness because of cancelled seasons.
Regret is not giving yourself a chance, and that is a powerful emotion that can inhibit happiness.
Therefore, I would suggest that you give it your all.
Then if you don't succeed at the level you want, you can walk away and not have regret.
If you do succeed, but don't have the heart to compete at college, don't take a scholarship regardless of feeling entitled.
I missed my entire HS senior year of CC and track because of sports being cancelled, but I stayed with it and did my best to overcome . However, I loved the competition and doing great.
Maybe the training you do is not what you want, or the distances that you race are not really what you wish for. We never ran more than 50 miles per week and had plenty of faster runs in the week. Slow runs are for joggers and do nothing for training racers. Better off with brisk walks.
Our HS coach had a runner sub 9 for 2-miles right away after he started coaching, but that runner got caught up in the anti-war protests. Coach moved and a couple of years later started at the HS I ran at, and again right away had a great runner go close to 9 minutes (almost broke 9 as a junior, and had mono during the winter as a senior and again just missed sub 9). In fact , the runner was ahead of Alberto Salazar until the last 60 meters in the IPI HS 2-mile, where the lack of training because of mono combined with the heat (over 90 degrees.
I was middle-distance, but I was the only person on the team who could keep pace with the aforementioned 2-miler because he was so fast on 4-7 mile runs. I was a junior his senior year, and he really pushed it. Unfortunately, in college the coaches were bringing in much older Kenyans who could do lots if mileage at high speeds, and his college coach was one of these coaches, and so this guy burnt out on high mileage and never reached his potential.
