CROSS-REFERENCE TO RELATED APPLICATIONS [0001] Not applicable STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not applicable REFERENCE TO SEQUENCE LISTING, A TABLE, OR A COMPUTER PROGRAM LISTING COMPACT DISK APPENDIX [0003] Not applicable BACKGROUND OF THE INVENTION [0004] This invention relates to equipment used by runners to get a good start in a sprint race. Initially starting blocks were developed for dirt tracks with large spikes driven into the dirt to keep them from slipping. Starting blocks generally evolved into assemblies with a central rail and a moveable block attached to each side as in U.S. Pat. No. 3,494,615 by G. L. Moore. With the advent of synthetic track surfaces starting blocks generally used shorter spikes to avoid damaging the track surface and often provided tilt angle adjustments for each foot block as in U.S. Pat. No. 4,611,803 by Newton, Jr. More recently, portable starting blocks small enough and light enough to be conveniently carried in a runners equipment bag have been developed for synthetic track surfaces. These are seen in U.S. Pat. No. 6,238,319 by Young and U.S. Pat. No. 6,342,029 by Richards. Related U.S. Patent Documents [0005] TABLE-US-00001 3,494,615 February, 1970 G. L.

They also generally allow some flat surfaces to rest on the track which contributes to slippage during the start of a race. The more recent portable blocks have the disadvantage of being difficult to position on the track because they are two completely separate foot blocks and have to be positioned separately. Powerful sprinters often displace the back foot block when starting. Since it is not attached to the front foot block in any way, it has to be repositioned after each such start. This is a significant disadvantage when doing repeat training starts or warmup starts for a race. SUMMARY OF INVENTION [0007] This invention provides a truly portable starting block with a central tie bar that makes it easy to position the assembly on the track. The tie bar also prevents the displacement of the back foot block so that it is never necessary to reposition it after a start. The only part of the entire assembly to touch the track are the spikes which are placed directly under and behind the sprinter's feet. This arrangement insures the securest possible anchorage to the track and eliminates slippage problems. [0008] The longitudinal separation of the foot blocks is accomplished by choosing from a series of holes in the tie bar when connecting the foot blocks to the tie bar. The tilt angle of the each foot plate is adjustable by selecting from a series on notches in the brace arm that secures the angle between the front and back plates of each foot block. [0009] Each foot block is easily removed from the tie bar and folded flat so that the three pieces can be stored in a small bag and easily carried in a runner's equipment bag.
