Accidents happen all the time, but I think 2 times of the year we are often more susceptible.
1 - Early in the season when we don't have our "bike legs" in the best form.
2 - Later in the season, when we are supposedly at the top our our annual
game, and take the extra risk.
Make a conscience effort to take your time, warm up, stretch, get your head in the game and remember that if you want to enjoy a terrific season ahead of us, and many more to come, practice the rules of moderation.
We all take chances, and perhaps many unnecessary risks. Luck and skill play vital roles in the outcomes, so the one variable you can help impact is timing....it's early in the season, chill for a bit.
