1. A hurdle for hurdle racing, comprising: two hollow base parts (1) arranged at a distance from one another and adapted to rest on a supporting surface, each base part comprising a hollow space;a counterweight (25) displaceably arranged in each base part (1);a driver means (21) for the counterweight (25);a gear transmission (22, 23, 40) arranged in each base part (1) and operatively connected to displace the counterweight (25);tubular elements (2, 3), each tubular element comprising a first tube (2) and a second tube (3) displaceable telescopically relative to one another, the first tube (2) and the second tube (3) extending vertically in relation to the supporting surface, each of the first tubes (2) being fixed to one end of an associated one of the base parts (1); locking elements (9, 10, 13, 15) that lock the first and second tubes (2, 3) relative to one another;a bar (4) connecting upper ends of the second tubes (3) situated furthest away from the associated base part (1);a strip-type force-transmitting means (20) that extends from the hollow space in each base part (1) and is connected to an associated second tube (3), the strip-type force transmitting means (20) provided with openings (29); andguides (24, 28) arranged in each base part (1),wherein the gear transmission (22, 23, 40) engages both with the strip-type force-transmitting means (20) and with the driver means (21) for the counterweight (25),wherein the strip-type force-transmitting means (20) is received in the guides (24, 28), andwherein the gear transmission (22, 23, 40) is adapted to cooperate with the openings (29) provided in the strip-type force transmitting means (20). 2. The hurdle according to claim 1, wherein the gear transmission includes two cog wheels (22, 23) having different diameters. 3. The hurdle according to claim 2, wherein the driver means comprises a rack (21) and one (22) of the two cog wheels (22, 23) is adapted to cooperate with the rack (21). 4. The hurdle according to claim 3, wherein, the guides arranged in each base part are radial guides, andthe radial guides (18, 19) are arranged at a transition between each first tube and the associated one of the base parts (1). 5. The hurdle according to claim 3, further comprising stationary parts (7) having holes, wherein each of the stationary parts (7) having holes (13) is mounted stationary to a respective one of the second tubes (3), andwherein the locking elements that lock the telescopic first and second tubes (2, 3) relative to one another comprise locking pins (9) that cooperate with the holes (13) in the stationary part (7). 6. The hurdle according to claim 3, wherein the locking elements include a spring-loaded locking arm (15) which can assume an active position and an inactive position. 7. The hurdle according to claim 2, wherein, the guides arranged in each base part are radial guides, andthe radial guides (18, 19) are arranged at a transition between each first tube and the associated one of the base parts (1). 8. The hurdle according to claim 2, further comprising stationary parts (7) having holes, wherein each of the stationary parts (7) having holes (13) is mounted stationary to a respective one of the second tubes (3), andwherein the locking elements that lock the telescopic first and second tubes (2, 3) relative to one another comprise locking pins (9) that cooperate with the holes (13) in the stationary part (7). 9. The hurdle according to claim 2, wherein the locking elements include a spring-loaded locking arm (15) which can assume an active position and an inactive position. 10. The hurdle according to claim 1, wherein, the guides arranged in each base part are radial guides, andthe radial guides (18, 19) are arranged at a transition between each first tube and the associated one of the base parts (1). 11. The hurdle according to claim 10, further comprising stationary parts (7) having holes, wherein each of the stationary parts (7) having holes (13) is mounted stationary to a respective one of the second tubes (3), andwherein the locking elements that lock the telescopic first and second tubes (2, 3) relative to one another comprise locking pins (9) that cooperate with the holes (13) in the stationary part (7). 12. The hurdle according to claim 1, further comprising stationary parts (7) having holes, wherein each of the stationary parts (7) having holes (13) is mounted stationary to a respective one of the second tubes (3), andwherein the locking elements that lock the telescopic first and second tubes (2, 3) relative to one another comprise locking pins (9) that cooperate with the holes (13) in the stationary part (7). 13. The hurdle according to claim 12, wherein the stationary part is a flat bar (7) and the flat bar (7) is arranged in a closed space within the tubular element (2, 3). 14. The hurdle according to claim 1, wherein the locking elements include a spring-loaded locking arm (15) which can assume an active position and an inactive position. 15. The hurdle according to claim 1, wherein the force-transmitting means (20) is a strip of spring steel.
