The Cherry Blossom 10K/5K is going virtual! Runners can complete their distances on their own schedule at the sanctioned course among the cherry trees near Shofuso, on their regular training courses, on a treadmill, or anywhere that feels right (while practicing social distancing, of course!). Between Saturday, April 10 and Sunday, April 18, complete your run/walk at your convenience, submit your time on our RunSignUp app via MapMyRun or your own timing, take some selfies along the way or at the finish with the hashtag #CherryBlossom10K or #SpringStartsatShofuso. We’ll share a Spotify playlist with some Japanese pump-up tunes to run to!

Race Swag!
All participants will receive a beautiful cherry blossom race t-shirt, Japanese pump up playlist, race bib PDF, and route map with selfie locations marked, as well as free admission to Shofuso during the 2021 season!

All proceeds benefit the Japan America Society of Greater Philadelphia, a 501(c)3 nonprofit organization, and Shofuso.

Referral Program

Take advantage of our new referral program, earn CASH BACK, and enjoy the cherry blossoms with your friends! While the Shofuso Cherry Blossom 10K/5K is an amazing, rewarding experience itself, it's even better when you have friends join you on your run/walk!  Refer friends and family to join you to earn rewards and enjoy the cherry blossoms in April. 

Here's how it works:

  1. Sign up for the Virtual Run. Once you complete your registration, you'll receive a unique URL link to share.
  2. Share this unique link with friends and family as often as you'd like.
  3. Each time someone signs up through your link, you'll accrue one referral. Earn five referrals and get $20 credited back to you. Easy right?!?!

Keep going and every 5 people you refer, you'll receive $20 back until your entire entry fee is refunded!
