There are some memorial events planned for this weekend. On Saturday, the EBBC is having a remembrance of Mark at the Martinez Amtrak station followed by a ride up McEwen, past the accident site on the descent, and continuing back via Franklin Canyon. See:

for details.
On Sunday, his club is holding a memorial ride starting in Danville:
"Hi Friends of Mark,
By now most everyone has heard the tragic news of Mark's passing.
This tragedy has had a profound effect on our club, we have lost a
great friend and loyal teammate. This Sunday, the team ride will be
a celebration of Mark's life and the strong bonds we shared with
him. The ride will start at Peet's (at 9:00am) in Danville (usual
meeting point) and head through Sunol to Calaveras and back (50 mile
loop).
Please respect the fact that this ride is about Mark, the pace will
be EASY so that we can all ride together and share memories and
stories. Jennie Phillips has been kind enough to bring black ribbons
for the ride. The ride will start at 9:00am, instead of the normal
8:00am start, we will roll at 9:10 am. The group will be large, so
please obey all traffic laws. We will ride two-abreast only where
bike lanes, road shoulders and terrain allow, but will otherwise ride
single-file. Please signal all significant road hazards to your
fellow cyclists well ahead of time, and please allow those familiar
with the route to ride at the front. We will also do our best to have
members of our club positioned at the back of the ride to ensure that
no one is left behind.
Please be aware that although we are making efforts to alert police
departments of our plans Sunday morning, this is not an official,
licensed event, and all riders who participate will be doing so at
their own risk.
Our thoughts and prayers are with Mark and his family. Mark was a
kind and generous person and will be missed more than words can
describe."
