Earlier this week, the son of a family friend suffered a sudden seizure. While he was at home at the time he is regularly out running or riding his bike.
You see the problem of course, if the seizure had hit while he was out exercising then no one would have known who he was, nor who to contact in an emergency.
The solution is to carry some form of readily accessible identification. One of most convenient options is the road-id, which has several products ranging from wrist bands to dog tags. There may be other options out there as well, but the road-id is affordable and excellent quality (I have the Wrist-Id Sport).
Considering that cyclists are regularly out by themselves and are a vulnerable road user on every ride, it's a small thing to carry for a lot of peace of mind for you and your family.
So, the next time you have a 'close call' on the bike, ask youself what would happen if you had an accident. Would emergency services personnel know whether you had any medical conditions and who to contact. Also consider your riding buddies. If they had an accident would you know who to call?
