There are a lot of bike rides that are coming up as it gets warmer and here are just a couple.
The last ever VASA ride. - April 7th
Sadly, this tradition is going away. It won't even be at the Swedish Embassy this year - instead it will be at the new REI. But there will still be blueberry soup. More info here.
The DC Bike Ride - May 17th
A 20 mile, car free, recreational bike ride with music and food.
