AB  - Cycling is a sport characterised by high training load, and adequate nutrition is 
      essential for training and race performance. With the increased popularity of 
      indoor trainers, cyclists have a unique opportunity to practice and implement key 
      nutritional strategies. This study aimed to assess carbohydrate (CHO) intake of 
      cyclists training or racing in this unique scenario for optimising exercise 
      nutrition. A mixed-methods approach consisting of a multiple-pass self-report 
      food recall and questionnaire was used to determine total CHO intake pre, during 
      and post-training or racing using a stationary trainer and compared with current 
      guidelines for endurance exercise. Sub-analyses were also made for higher ability 
      cyclists (>4 W/kg functional threshold power), races v. non-races and 'key' 
      training sessions. Mean CHO intake pre and post-ride was 0.7 (sd 0.6) and 1.0 (sd 
      0.8) g kg/BM and 39.3 (sd 27.5) g/h during training. CHO intake was not different 
      for races (pre/during/post, P = 0.31, 0.23, 0.18, respectively), 'key sessions' 
      (P = 0.26, 0.89, 0.98) or higher ability cyclists (P = 0.26, 0.76, 0.45). The 
      total proportion of cyclists who failed to meet CHO recommendations was higher 
      than those who met guidelines (pre = 79 %, during = 86 %, post = 89 %). Cyclists 
      training or racing indoors do not meet current CHO recommendations for cycling 
      performance. Due to the short and frequently high-intensity nature of some 
      sessions, opportunity for during exercise feeding may be limited or unnecessary.
