-## Upcoming workshop
-
-We're running a [2020 SAMPL virtual workshop on Nov. 4](https://www.gdch.de/gcc2020) in combination with the GCC.  It’s timed so both European and US folks can join, and will be hot on the heels of the current SAMPL7 physical properties challenge. Sign up if you're interested in attending.

 ## Challenge overview
 
-The SAMPL7 phase of challenges currently includes a physical property challenge on pK<sub>a</sub>, partitioning, and permeability.
-
-Recently concluded SAMPL7 challenges include a protein-ligand component on PHIP2, as well as host-guest binding on three systems: A pair of Gibb Deep Cavity Cavitands (GDCCs), a new "TrimerTrip" molecule from Lyle Isaacs and his group, and a series of cyclodextrin derivatives from Mike Gilson's group. Each host binds one or more guests, and each system involved a total of 9-20 binding free energy calculations.

-The planned later stage of SAMPL7 focused on GSK physical property data is being shifted to SAMPL8 because of availability of a more time-sensitive physical property dataset which was used here.
