%X Purpose: We intended to determine predictor variables of anthropometry and training for marathon race time in recreational female runners in order to predict marathon race time for future novice female runners.
%X Methods: Anthropometric characteristics such as body mass, body height, body mass index, circumferences of limbs, thicknesses of skin-folds and body fat as well as training variables such as volume and speed in running training were related to marathon race time using bi- and multi-variate analysis in 29 female runners.
%X Results: The marathoners completed the marathon distance within 251 (26) min, running at a speed of 10.2 (1.1) km/h. Body mass (<italic>r</italic>=0.37), body mass index (<italic>r</italic>=0.46), the circumferences of thigh (<italic>r</italic>=0.51) and calf (<italic>r</italic>=0.41), the skin-fold thicknesses of front thigh (<italic>r</italic>=0.38) and of medial calf (<italic>r</italic>=0.40), the sum of eight skin-folds (<italic>r</italic>=0.44) and body fat percentage (<italic>r</italic>=0.41) were related to marathon race time. For the variables of training, maximal distance ran per week (<italic>r</italic>=? 0.38), number of running training sessions per week (<italic>r</italic>=? 0.46) and the speed of the training sessions (<italic>r</italic>= ? 0.60) were related to marathon race time. In the multi-variate analysis, the circumference of calf (<italic>P</italic>=0.02) and the speed of the training sessions (<italic>P</italic>=0.0014) were related to marathon race time. Marathon race time might be partially (<italic>r</italic>

%X Conclusions: Variables of both anthropometry and training were related to marathon race time in recreational female marathoners and cannot be reduced to one single predictor variable. For practical applications, a low circumference of calf and a high running speed in training are associated with a fast marathon race time in recreational female runners.
