Final answer:
Tim is likely to recommend sprinting drills and weight lifting to improve Susan's final sprint and overall power, respectively, in her bicycle races.
Step-by-step explanation:
Based on Susan's performance where she kept pace during the majority of the race but fell behind during the final sprint, Tim, as her coach, would most likely recommend that she include sprinting drills in her training regimen. Sprinting drills will help Susan improve her anaerobic capacity and explosive speed which is essential for the last burst of speed in a race. To optimize her overall strength and power, which can also contribute to a more powerful sprint, Tim might also suggest she incorporates some weight lifting into her training plan.
