I've always wanted to because it sounds fun and would be a great way to socialize with local runners, but I never have. I like the idea of a series, though.

There are 3 running clubs just in my area. They are a lot of fun and its fun to see the same people each week. Its always followed by socializing and a few beers. They get a decent crowd too. Attendance is up to 150-200. My favorite is held at a reservoir and its gorgeous running there.

Only in August, they are 3 1-mile races. There are awards at individual races but cumulative awards are given for the entire series and it's based on the three races added up. The ceremony after the last race is really fun and the awards are cash ($500, $200, $100, $50). Not bad for a small local outfit. It's my favorite part of the racing year!

That sounds super fun!

We don't have anything like that here that I am aware of. I know the kids have a "Gran Prix" that is a once a month for 6 months series of 1 miler races and if they complete all 6, they get a special medal. My youngest is 5 and he is old enough this year to do them, which he keeps begging me to let him do. Since all my races are bigger, and fewer, and never on his race days, I get to run them with him yay! I am so excited! Probably  more excited to do his than mine even!

Unless you're willing to train through many of them treating them as hard training runs and only taper and rest for one every 3-4 weeks, I'd stay away from weekly series that extend that long. Weekly races can have more of an effect, and not always good, on your training and often lead to stagnation or even slowing times depending on what kind of shape you're in at the beginning of the series.

I definitely won't be  racing all of them. I like to use them for tempo runs and race like one every three weeks. I agree that it can burn you out quick if you let it too. I once did a twelve week series without missing a week and it was brutal.

There is a weekly race in Cambridge (2.5 & 5 miles) year round which is really cool. I have run there many times but only ran the race once. My town has at least 8 races, and 2 of them are walking distance from home which I look forward to doing. (moved here a year ago). My running club has monthly races, and I love doing as many of those that I can.

Ohio has a neat series called the Subway Challenge series.  It's more of a year long series, but most runners typically do between 10-20 of the 60 available races.  I've been tempted to give it a try, but I just don't race that often and prefer focusing on my marathon training cycles.  It has some pretty good prize money though, which is a nice draw.  In the "elite" category, you're eligible for $200 for every race you win, and then a larger, series purse at the end of the year.
