Table schema:
CREATE TABLE table_name_14 (heat VARCHAR, lane VARCHAR, mark VARCHAR, name VARCHAR)

Question: When the lane is under 2 and the name is virgen benavides with a mark of 7.29, what's the total number of Heat found?
SQL: SELECT COUNT(heat) FROM table_name_14 WHERE mark = "7.29" AND name = "virgen benavides" AND lane < 2
