Trapz: just one option of many...heavy DL's don't always work for everyone.

3X8-10 rep, at a fast pace. This is actually pre-exhaustion, applied to a SS.
Calvez
Other than running in sand or up stiff inclines (better options..my view only), might suggest the all day program.
Every hour, on the hour, do a couple of light set of one legged calf raises, 12 rep, full. Continue this for at least 6-8 hours. Idea is to keep the blood in the area most of the day, keeping the pump best you can.. (old BB'ing saying, More Blood, More Muscle). Massage the area between sessions. Can also apply a warming agent; lotion, sports rub, etc to keep the area warm. Might try this program once a week, an nothing else or the calves, and notice how the calves respond.
Suggest, anytime doing calf raises, to do them one leg at a time...rather than both at the same time. Better focus on each leg seems to work well for a number of guys.
Also, there's a very good calf thread on GB, might want to check it out.
Good LuckZ
