Don't won't to race?
Don't. Use it as your workout! Think about it.
- The course is marked and protected (police coverage, volunteers at the corners, etc.)
- There are usually timers or mile markers
- There are usually water stops
It does cost a nominal fee but look at the advantages you gain.
Not sure about running alone?
Depending upon the size of the race, there will be someone running your pace. You may not find them at the start but surely along the course you can find who is running your pace.
Give it a shot.
Think about taking your workout to the races.
Once the entry fee is paid, you get all the assistance you need. The only thing left for you to do is to stick to your workout plan. Do not get caught up in the race!
May the roads/trails be kind to you!
